Historical Development
In ancient times, bone meal and eggshell ash were often used to supplement calcium. In modern times, chemistry has flourished, and people know that calcium and phosphorus can supplement together. Craftsmen then made Dicalcium Phosphate DCP, which was initially used only as medicine. Later, it was found to be beneficial to animal husbandry, and gradually became widely used in feed. After a hundred years of improvement, the craftsmanship has become more refined and the quality has become better.
Product Overview
Dicalcium Phosphate DCP is a white or off-white powder, odorless and tasteless, difficult to dissolve in water, easily soluble in dilute hydrochloric acid, rich in phosphorus and calcium, stable in nature, can supplement calcium and phosphorus for medicinal use, and can strengthen the bones of poultry and livestock for feed, making it a good product for dual use.
Physical & Chemical Properties
Dicalcium Phosphate DCP has high density, heavy texture, smooth feel, high melting point, does not melt in fire, is not easy to deteriorate in the air, sinks to the bottom when mixed with water, and its insoluble nature makes it slowly dissolve in the gastrointestinal tract and easily absorbed.
Technical Specifications & Labeling
Dicalcium Phosphate DCP standards: pharmaceutical grade products need to measure heavy metal content (not exceeding 10 parts per million) and fineness (passing a 100-mesh sieve); feed grade products need to measure phosphorus (not less than 18%) and calcium (not less than 23%). The label must contain the full name Dicalcium Phosphate DCP, with grade, index, production period and storage method attached.
Preparation Method
Dicalcium Phosphate DCP is usually prepared with phosphoric acid and calcium hydroxide as raw materials. They are put into a reaction pot in proportion and stirred at room temperature until the solution is neutral. After precipitation, filtration, washing and drying, Dicalcium Phosphate DCP is obtained. Pharmaceutical grade products still need to be purified and impurities removed.
Chemical Reactions & Modifications
Dicalcium Phosphate DCP reacts with strong acid to form soluble phosphates. When it meets oxalic acid, it forms calcium oxalate precipitates. When it is heated with carbon at high temperature, it can form calcium phosphide, which is its normal state.
Synonyms & Product Names
Dicalcium Phosphate DCP is also known as "calcium hydrogen phosphate", but in paper transactions, the full name Dicalcium Phosphate DCP must be used to distinguish it from other substances.
Safety & Operational Standards
When handling Dicalcium Phosphate DCP, pharmaceutical grade products must be handled aseptically to prevent contamination; feed grade products must be handled with gloves to prevent dust from entering the lungs. If it accidentally enters the eyes, rinse it with clean water quickly and wash your hands after handling.
Application Area
Dicalcium Phosphate DCP can be used as a medicine to make calcium tablets and oral liquids to supplement the body's calcium and phosphorus deficiencies and treat osteoporosis; it can be mixed into pig, chicken, and cattle feed for growth and development. It is also used in aquaculture to help fish and shrimp shed their shells and grow.
Research & Development
Students and craftsmen are exploring new uses for Dicalcium Phosphate DCP, such as its application in bioceramics. At the same time, they are also exploring new methods to increase yields and reduce costs, so that both medicinal and animal feed users can fully play their own advantages.
Toxicity Research
Dicalcium Phosphate DCP has extremely low toxicity, but excessive intake may cause stones. Therefore, it must be used in accordance with doctor's advice for medicinal use, and it must be used in proportion for animal feed and properly stored to prevent children from accidentally ingesting it.
Future Prospects
With the increase in population and the prosperity of animal husbandry in the future, the demand for Dicalcium Phosphate DCP will surely increase steadily. Its production process will become more environmentally friendly, and the medicinal grade may be more refined, and the animal feed grade may be cheaper, benefiting many parties.

How to control the reaction conditions when preparing Dicalcium Phosphate DCP?
This product is made by using phosphoric acid and calcium carbonate as materials, which are placed in a stone reaction tank in proportion. Phosphoric acid needs to be diluted to a concentration of 50%, and then slowly added with a wooden spoon, stirring while adding, and stopping when the pH value of the solution is about 6.5. At this time, the solution is like milk. Continue to stir for an hour to make the generated fine particles condense, and then let it settle. Discard the supernatant, take the precipitate and wash it three times, dry it in the sun, and grind it into powder to get Dicalcium Phosphate DCP. The process is like making curd cheese. If the temperature is too low, the reaction will be slow, and if it is too high, the particles will be coarse and hard. Only those that get the right temperature are the best products, with fine powder and appropriate calcium-phosphorus ratio.
What is the effect of Dicalcium Phosphate DCP in feed?
This product is a key additive for livestock and poultry feed. It is rich in phosphorus and calcium, and the ratio of the two is close to two to one, which is easy to absorb. When used in chick feed, the addition amount is 1.5%, which can promote bone development and reduce soft leg disease; when used in sow feed, it can increase lactation and improve piglet survival rate. Its powder is fine and evenly mixed with feed, without dust, and livestock and poultry do not reject it. In aquatic feed, it can withstand water immersion and does not dissolve, so that the absorption rate of fish and shrimp reaches more than 80%. Compared with other calcium and phosphorus additives, it is less irritating and suitable for various livestock and poultry, so it is a must for the feed industry.
What are the advantages of Dicalcium Phosphate DCP compared with other calcium salts?
Compared with calcium carbonate, Dicalcium Phosphate DCP has a slightly lower calcium content, but it is rich in phosphorus, and one feed supplements two elements without the need for additional phosphorus. Compared with calcium hydrogen phosphate, its calcium-phosphorus ratio is more balanced, suitable for young animals, and the absorption and utilization rate is 15% higher. In acidic gastric juice, its solubility is better than tricalcium phosphate, and it can release nutrients quickly, so it is particularly suitable for broiler fattening period. Its powder has good fluidity and is not easy to agglomerate when mixed with feed. It is more durable than calcium lactate and does not need to be refrigerated, so it has lower cost and better cost performance.
What are the differences between different production processes of Dicalcium Phosphate DCP?
The Dicalcium Phosphate DCP powder produced by the wet method is finer and has high purity, which is suitable for feed and food; the Dicalcium Phosphate DCP powder produced by the dry method is slightly coarser and contains a small amount of impurities, which is suitable for fertilizer. The wet method needs to be precipitated and washed to remove chloride ions, so it can be used for aquatic feed; the dry method is directly calcined, and the chloride ion residue is high, which is only suitable for terrestrial animals. In addition, the calcium and phosphorus produced with bone meal as raw material are easier to absorb, but the cost is higher; the ore as raw material has stable purity and low cost, each has its own advantages, and it should be selected according to the purpose.
How to prevent agglomeration of Dicalcium Phosphate DCP during storage?
This product needs to be packaged in thick plastic bags, each bag is 50 kilograms, the bag mouth is tightly tied, and the outer cover is a woven bag. Store in a dry warehouse, with wooden boards on the floor to prevent moisture, and oil paper on the boards to keep the materials one foot off the ground. The stack height should not exceed eight layers to prevent the bottom layer from being pressed and agglomerated. The warehouse is equipped with a calcium chloride moisture absorption tank, and ventilation is carried out twice a week during the rainy season. If there is slight agglomeration, the bag can be gently rubbed to loosen the particles, but it should not be hit hard to prevent the powder from becoming coarse. Although its hygroscopicity is weak, it still needs to be checked frequently for a long time. If it is damp, it should be moved to a ventilated place to dry to keep it loose as before.
