Frequently Asked Questions

Q: What is Phosphoric Acid?

A: Phosphorous acid is in Colorless, transparent and syrupy liquid or rhombic crystalline;Phosphorus acid is odorless and tastes very sour; its melting point is 42.35℃ and when heated to 300℃ phosphorous acid will become into meta phosphoric acid; its relative density is 1.834 g/cm3;phosphoric acid is easily soluble in water and resolves in ethanol; Phosphate acid may irritate human skin to cause phlogosis and destroy the issue of human body; phosphorus acid shows corrosiveness being heated in ceramic vessels; phosphate acid has got hydroscopicity.



Q: Use?
Technical grade phosphoric acid may be used to produce variety of phosphates, electrolyte treatment liquids or chemical treatment liquids, refractory mortar with phosphoric acid and inorganic coheretant.Phosporic acid is also used as a catalyst, drying agent and cleaner. In coating industry phosphoric acid is used as a rust-proof coating for metals; As a acidity regulator and nutrition agent for yeast food grade phosphoric acid may be applied to flavors, canned food and light drinks as well as used in wine brewery as a nutrients source for yeast to prevent the reproduction of useless bacteria.



Phosphates are basically compounds of phosphorus and oxygen that occur in many forms and are usually combined with other elements. We offer a wide range of phosphate compounds such asSODIUM HEXAMETAPHOSPHATE,SODIUM HYDROGEN PHOSPHATE,SODIUM PYROPHOSPHATE and so on.
