Phosphorus chemical products are mainly divided into two categories: one is used in agriculture, such as phosphate fertilizers or phosphorus-containing pesticides represented by monoammonium phosphate, diammonium phosphate and dicalcium phosphate, such as glyphosate, etc.;

With the development of science and technology, high-purity and special functional phosphorus chemical products have been further promoted and applied in cutting-edge science and national defense industry, and a large number of new products have appeared, such as: phosphorous acid and hypophosphorous acid and their salts, electronic grade yellow phosphorus, red phosphorus, metal phosphide, organic phosphide, pharmaceutical grade phosphide and other products, phosphorus chemical products play an increasingly important role in people's clothing, food, housing and transportation.
