1. It is the production of important agricultural phosphate fertilizer (calcium superphosphate, potassium dihydrogen phosphate) of raw materials, but also the production of feed nutrition agent (MCP) raw materials.

2. Industry: phosphoric acid is an important chemical raw material, the main function is as follows:

(1) The surface of metal is treated, and the hard soluble phosphate film is produced on the metal surface to protect the metal from corrosion.

(2) The mixture of nitric acid is used as a chemical polishing agent to improve the finish of the metal surface.

(3) Producing phosphates of raw materials for washing products and insecticides.

(4) The raw materials for the production of phosphorus containing flame retardants.

3. Food: phosphoric acid is one of the food additives. As an acid and yeast nutrient in food, phosphoric acid is contained in Coca-Cola. Phosphate is also an important food additive, which can be used as a nutritional enhancer.

4. Medicine: phosphoric acid can be used for the preparation of phosphorus containing drugs, such as sodium glycerol phosphate.
