Agriculture: Phosphoric acid is the raw material for the production of important phosphate fertilizers (superphosphate, potassiumdihydrogen phosphate, etc.) as well as for the production of feed nutrients (monocalcium phosphate).
Industry: Phosphoric acid is an important chemical raw material, the main role is as follows:
Metal surfaces are treated to create insoluble phosphate films on the metal surface to protect the metal from corrosion.Mix with nitric acid as a chemical polish to improve the finish of metal surfaces.Production of detergents, pesticides raw phosphate.Production of phosphorus flame retardant raw materials.
Food: Phosphoric acid is one of the food additives, as acidifier in food, yeast nutrient, Coca-Cola contains phosphoric acid.
Phosphates are also important food additives that can be used as nutrition enhancers.
Medicine: Phosphoric acid can be used to make phosphorus-containing drugs, such as sodium glycerophosphate and so on.
