1. Phosphoric acid is the raw material for the production of important phosphate fertilizer (superphosphate, potassium dihydrogen phosphate, etc.), and also the raw material for the production of feed nutrients (calcium dihydrogen phosphate).
2. Treat the metal surface and generate a refractory phosphate film on the metal surface to protect the metal from corrosion.
3. Mixed with nitric acid as a chemical polish to improve the finish of the metal surface.
4. Production of raw material phosphate for washing supplies and pesticides.
5. Raw materials for producing phosphorus-containing flame retardants.
6. On food, phosphoric acid is one of the food additives. As a sour agent, yeast nutrition, can be used as a nutrient enhancer.
7. Medicine: Phosphoric acid can be used to make phosphorus-containing drugs, such as sodium glycerophosphate.
