Application：
1. Phosphoric acid is the raw material of important phosphate fertilizer (superphosphate, potassium dihydrogen phosphate, etc.) and feed nutrient (calcium dihydrogen phosphate).
2. Treat the metal surface to form insoluble phosphate film on the metal surface to protect the metal from corrosion.
3. Mix with nitric acid as a chemical polish to improve the finish of metal surface.
4. used to product washing supplies, phosphate ester which is raw material of pesticide
5 Raw materials for producing phosphorus flame retardants.
6.Phosphoric acid is one of the food additives. It is used in food as an acid flavor agent and yeast nutrition agent. Phosphates are also important food additives and can be used as nutrient enhancers.
