Agriculture: phosphoric acid is the raw material for the production of important phosphate fertilizer (calcium superphosphate, potassium dihydrogen phosphate, etc.), and also for the production of feed nutrients (calcium dihydrogen phosphate). Industry: phosphoric acid is an important chemical raw material. Its main functions are as follows: The metal surface is treated to form insoluble phosphate film on the metal surface to protect the metal from corrosion. Mixed with nitric acid as a chemical polish to improve the finish of the metal surface. Production of washing supplies, pesticides raw materials phosphate ester. Production of phosphorus flame retardant raw materials
