Application Fields

Agriculture: Phosphorus is a raw material for producing important phosphate fertilizers (such as calcium superphosphate, potassium dihydrogen phosphate, etc.), and is also used in the production of...

Raw material for feed additive (Dicalcium Phosphate).

Industry: Phosphoric acid is an essential chemical raw material, primarily used for the following purposes:

1. Treat metal surfaces to form a non-soluble phosphate film on the surface, protecting the metal from corrosion.

2. Mixed with nitric acid as a chemical polishing agent to enhance the smoothness of metal surfaces.

3. Phosphates, raw materials for producing detergents.

4. Raw materials for flame-retardant agents containing phosphorus.

Food: Phosphates are one of the food additives, used as a flavoring agent and yeast nutrient in foods, and are also present in colas. Phosphates are also significant food additives, serving as nutritional enhancers.
