What is phosphate CAS 7779-90-0?

The natural mineral of Zinc phosphate is called "Paraphosphorite", which has two types: alpha type and beta type. Zinc phosphate is a colorless orthorhombic crystal or white microcrystalline powder. Dissolve in inorganic acids, ammonia water, and ammonium salt solutions; Insoluble in ethanol; It is almost insoluble in water, and its solubility decreases with increasing temperature.

Application

Zinc phosphate can be obtained by reacting phosphoric acid solution with zinc oxide, or by reacting trisodium phosphate with zinc sulfate. It is used as a base material for coatings such as alkyd, phenolic, and epoxy resins, and is used in the production of non-toxic anti rust pigments and water-soluble coatings. It is also used as a chlorinated rubber and high polymer flame retardant. Zinc phosphate is used as an analytical reagent
