Historical Development
Since the advent of chemistry, the production of phosphate fertilizers has been gradually perfected. By the end of the 19th century, Europeans began to use phosphoric acid and ammonia to react to obtain ammonium orthophosphate to nourish farmland. Later, scientists studied the phosphoric acid polymerization reaction and developed ammonium polyphosphate, which was called Normal Ammonium Polyphosphate. In the mid-20th century, industrial progress and advanced technology made it possible to produce large-scale products in a continuous manner, with stable product properties, convenient application, and slow nutrient release, which is conducive to crop absorption. Then the formula was innovated, and the structure of the polymer chain became more reasonable, which not only enhanced its solubility, but also reduced nutrient loss. Today, Normal Ammonium Polyphosphate has become a representative of high-efficiency phosphate fertilizers worldwide, helping to promote sustainable agricultural development and benefit all people.
Product Overview
Normal Ammonium Polyphosphate, Chinese translation of conventional ammonium phosphate, is mostly white powder or granular, stable in nature, soluble in water, easy to agglomerate in case of moisture. It is obtained by the reaction of phosphoric acid and ammonia, and has both excellent slow-release and excellent fire resistance. Widely used in the preparation of agricultural fertilizers, it can effectively replenish nutrients required by soil, promote crop growth and development, and can also be used as an industrial flame retardant to improve the fire resistance grade of materials. This product has both environmental advantages, and the release of ammonia and phosphorus is stable during application, and the pollution is minimal. It should be sealed and moisture-proof during storage, and should not coexist with strong acids or flammable products. Because of its mild nature and diverse uses, it is favored by the market. It is a high-quality additive commonly used in agriculture, building materials and other industries.
Physical & Chemical Properties

Preparation Method
Take phosphoric acid and ammonia water as raw materials, first combine them in a reaction kettle in an appropriate ratio, stir slowly, and control the temperature from 60 to 80 degrees Celsius, so that the two can interact to form a primary salt of ammonium phosphate. Then, heat up to more than 180 degrees Celsius, dehydrate and condense to form ammonium polyphosphate. In the meantime, the catalyst can be used sulfuric acid or solid acid to accelerate the polycondensation reaction, which is conducive to the formation of chain-like structures. After the reaction is completed, it is cooled under reduced pressure to obtain white powdery positive ammonium polyphosphate. The whole process needs to control moisture and impurities, prevent side reactions, and keep the product pure. This method is prepared by simple process, high conversion rate, and the product is easily soluble in water. It is suitable for flame retardant and fertilizer addition.
Chemical Reactions & Modifications
Normal Ammonium Polyphosphate, chemically known as ammonium orthophosphate polymer, is formed by the condensation of phosphoric acid and ammonia at high temperature, and the form is mostly white powder. Its essence is stable, soluble in water, and decomposes at high temperature to release ammonia and phosphoric acid. In chemical reactions, ammonium orthophosphate is precipitated every time it encounters acid, and can be converted into a variety of phosphates when it encounters alkali. If it is modified, silicone, quaternary ammonium salt or metal ions are often introduced to increase its flame retardant, anti-caking and dispersion properties. After modification, its thermal stability is greatly increased, its hygroscopicity is weakened, and the decomposition temperature is increased, which has excellent flame retardant benefits. Widely used in plastics, rubber and coatings, the products are not only environmentally friendly, but also improve material properties. The method of chemical reaction and modification makes it infinite and inexhaustible.

What are the Chemical Properties of Normal Ammonium Polyphosphate?
Normal Ammonium Polyphosphate, the Chinese name is conventional ammonium polyphosphate, its chemical properties are very mysterious. Its chemical formula is mostly (NH PO 😉) _n, which is a polymer, chain structure, cation is ammonium ion, anion is linear polyphosphate. Its properties are white powder or particles, easily soluble in water, and the solution is neutral or slightly alkaline. When heated, ammonia gas can be released and gradually converted into metaphosphoric acid and orthophosphate. When decomposed by heat, the degree of polymerization decreases, and finally ammonium orthophosphate is formed. Under high temperature, there is also a dehydration reaction to form ammonium metaphosphate or polymer.
When it interacts with water, the chain structure can be broken to form polyphosphates and orthophosphates at all levels. Polyphosphate can complex metal ions, so it has a good chelating effect and is widely used in water treatment and scale inhibition. It can react with calcium and magnesium plasma to form insoluble precipitation; and with iron, aluminum, etc., can also react to form complexes. Common in fire retardants, fertilizers and feed industries.
Conventional ammonium polyphosphate encounters strong acid, and the chain is broken, slowly generating ammonium orthophosphate and phosphoric acid, releasing ammonia gas; in case of strong alkali, it is easy to hydrolyze and generate orthophosphate. High temperature incineration can release non-flammable gases such as ammonia, which can isolate air and is often used for flame retardancy. It is non-corrosive, has high safety performance, has good chemical stability, and is not easy to deteriorate after long storage.
Its synergistic effect can not only slow the release of nutrients in the soil, but also enhance the soil's ability to exchange cations. Its excellent slow-release properties help the soil release nutrients in sequence, making it the best fertilizer. It is nearly neutral in nature, has no obvious volatile toxic gases, and is environmentally friendly. Looking at its properties, it has the characteristics of polymer compounds, and also has the wonderful use of soap salts and complexes. It is a chemical with a wide range of uses.

What are the Applications of Normal Ammonium Polyphosphate in Industry?
As the saying goes, there are many kinds of ammonium salts, which are combined with nitrogen and phosphorus, and are used in many industrial fields. The common ammonium phosphate salts, including ammonium polyphosphate, are white powders or granules, easily soluble in water, and have stable chemical properties. The name of ammonium polyphosphate is "Normal Ammonium Polyphosphate", which produces long chain molecules that are heated and condensed by phosphoric acid and ammonia to cope with their differences. Its application can be divided into several ends.
One, it is used as a fireproof and flame retardant material. Ammonium polyphosphate is added to polymer materials to form polyphosphoric acid, and a non-flammable shell is formed on the way to the baking, preventing the spread of combustion. Widely used in plastics, rubber, wood, fiber and coatings. Secondly, ammonium polyphosphate is used in combination with pentaerythritol, melamine, etc., and is compounded as a flame retardant to enhance the flame retardant properties of the material. It is widely used in electronic and electrical and transportation consultations.
Second, it can be used as a high-efficiency phosphate fertilizer. Meltwater is quick-soluble, nutrients are easily absorbed by crops, and phosphorus release is slow, not easy to lose. Helps crops grow rhizomes, fruits are firm, and yields are significantly increased. In addition, ammonium polyphosphate is easily blended with other nitrogen and potassium fertilizers to make compound fertilizers. Soil adaptability is wide, especially suitable for dryland and alkaline soil application.
Third, used in water treatment. Ammonium polyphosphate solution can chelate metal ions and inhibit the formation of scale such as calcium and magnesium, so it can be used as an anti-scale agent. It is used in boilers, cooling towers and circulating water systems to prolong the life of equipment and reduce energy consumption and operation and maintenance costs.
Fourth, it is also used as a cement admixture in the building materials industry. Ammonium polyphosphate regulates the hydration process and improves the workability and strength of cement. It is also used in the paper industry to assist in the dispersion of pulp and improve the quality of products. In oil drilling fluids, it is used as a corrosion inhibitor and viscosity regulator to ensure the stability of drilling equipment.
Necessary, Normal Ammonium Polyphosphate is lazy and widely used. Or applied to the broad field of agriculture, or supplemented by industrial tasks, such as flame retardant, slow release, water treatment, building materials, etc., are all valued by people.

What are the precautions for storage and transportation of Normal Ammonium Polyphosphate?
Normal Ammonium Polyphosphate is a commonly used compound fertilizer. It is stable in nature, but it must be handled, stored and transported with caution to ensure safety and prevent qualitative change. I would like to mention its precautions as follows:
1. Storage must be in a cool and dry place, away from fire and heat sources. It should not be damp. It is easily soluble in contact with water. If it is wet for a long time or causes agglomeration, it will even deteriorate and lose its original use. It is particularly important to ventilate the warehouse to prevent the accumulation of moisture, the intrusion of the smell of elastic soil, and the harm of flies, ants and rats.
2. It should not be stored with acids, alkalis, corrosive substances, flammable and explosive materials. Although its properties are stable, it is easy to decompose in case of strong acids, release harmful gases, and damage people's safety. It should be stacked in a reasonable area, leaving a moderate gap, and covered with a moisture-proof cloth to prevent sundries from infiltrating.
Third, special equipment should be used for handling carefully, and it should be handled with care to prevent damage to the packaging. If there is any residue, it should be cleaned up in time, and it should not harm people and animals. The packaging should be tight and tight, without the risk of leakage, and the stacking height should comply with the specification to avoid excessive pressure. Even if it is accidentally dumped, it will not fly and spread.
Fourth, when transporting, it must be firmly sealed, and the package must not be exposed, and it must not be mixed with food, drinking water, animal feed, etc. The means of transportation must be cleaned, and there should be no oil stains or impurities left. In case of rain and snow, a rainproof canvas must be covered. Strictly prevent fires on the way, and avoid fireworks
5. Stored in the warehouse, it must be stacked in an orderly manner according to the batch and the time of entering and leaving the warehouse, which is convenient for rotation. First-out, first-use. If you stay for a long time, it is advisable to check its properties regularly. If you see discoloration, agglomeration and other abnormalities, you should find out the cause and deal with it properly. Internal management personnel are responsible for registration and storage.
6. Warning signs should be set up in the factory area to educate operators, etc., and the operation rules should be clear. If you eat or touch it by mistake, you should wash it immediately or send it to the hospital, burn the waste packaging or dispose of it. It should be in accordance with environmental protection regulations and cannot be left out of the field without authorization.
In summary, although Normal Ammonium Polyphosphate has good solids, it is necessary to pay attention to the details of storage and transportation. Detailed protection is required to ensure safety and benefit agricultural production.

How Does Normal Ammonium Polyphosphate Affect Plant Growth?
It is often said that phosphorus is an essential element for plant growth. Nowadays, normal ammonium polyphosphate (APP) is based on phosphate and contains nitrogen. When dissolved in water, polyphosphate and ammonium ions are released, which can not only be needed by plants, but also improve soil structure. Its benefits are many, but it has a huge impact on plant growth.
After APP enters the soil, due to its phosphorus accumulation characteristics, it releases phosphorus slowly and can last for a long time. It is better than elemental phosphorus fertilizer. The plant root system can gradually absorb it, while the phosphorus is free from sudden gains and losses. At the initial planting stage, phosphorus can promote the development of roots and seedlings, make the main roots strong and fibrous roots clump, and it is more effective to explore water nutrients in the ground. If the mature stage, phosphorus will be transformed into factors that promote flowering, fruiting, strong stems and thick leaves, so that the plant consumes energy to a certain extent and the harvest is prosperous.
Ammonium ions can not be ignored, it is an important source of nitrogen. Both nitrogen and phosphorus can work synergistically to make the leaves rich, photosynthetic, and protein synthesis vigorous. APP in the field, easy to be taken up by root hairs, and not easy to lose to rain, so that crops often get nutrients, not withering. And its phosphorus chain structure, so that the microorganisms in the soil can be decomposed and transformed, contributing to the balance of micro-ecology and improving soil fertility.
However, the appropriate use must also be judged by the situation. If the concentration is too high, or improper application, it is easy to cause soil acidification, root system hindrance, and loss of growth. If polyphosphate encounters heavy metal ions, there is a risk of fixing phosphorus, which makes the plant absorb poorly and should be prepared according to the soil conditions.
All in all, ammonium polyphosphate is a new cutting-edge of modern agricultural fertilizers, which can provide plants with slow release of phosphorus and quick-acting nitrogen, helping their roots to be deep and leafy and full of vitality. If it is combined with crop rotation and adjusted application, the years will be abundant and the harvest can be expected. Reasonable and good use can make the growth of the grain and the prosperity of vegetables and fruits suitable.
After APP enters the soil, due to its phosphorus accumulation characteristics, it releases phosphorus slowly and can last for a long time. It is better than elemental phosphorus fertilizer. The plant root system can gradually absorb it, while the phosphorus is free from sudden gains and losses. At the initial planting stage, phosphorus can promote the development of roots and seedlings, make the main roots strong and fibrous roots clump, and it is more effective to explore water nutrients in the ground. If the mature stage, phosphorus will be transformed into factors that promote flowering, fruiting, strong stems and thick leaves, so that the plant consumes energy to a certain extent and the harvest is prosperous.
Ammonium ions can not be ignored, it is an important source of nitrogen. Both nitrogen and phosphorus can work synergistically to make the leaves rich, photosynthetic, and protein synthesis vigorous. APP in the field, easy to be taken up by root hairs, and not easy to lose to rain, so that crops often get nutrients, not withering. And its phosphorus chain structure, so that the microorganisms in the soil can be decomposed and transformed, contributing to the balance of micro-ecology and improving soil fertility.
However, the appropriate use must also be judged by the situation. If the concentration is too high, or improper application, it is easy to cause soil acidification, root system hindrance, and loss of growth. If polyphosphate encounters heavy metal ions, there is a risk of fixing phosphorus, which makes the plant absorb poorly and should be prepared according to the soil conditions.
All in all, ammonium polyphosphate is a new cutting-edge of modern agricultural fertilizers, which can provide plants with slow release of phosphorus and quick-acting nitrogen, helping their roots to be deep and leafy and full of vitality. If it is combined with crop rotation and adjusted application, the years will be abundant and the harvest can be expected. Reasonable and good use can make the growth of the grain and the prosperity of vegetables and fruits suitable.
