ZINC PHOSPHATE, MONOBASIC

Description

Zinc phosphate,monobasic is a white triclinic crystal system or a white solidified substance, deliquescence, and decomposes at 100 ℃ and water. It contains high free acid and is highly corrosive. It is used as an analytical reagent and preservative, also in the glass and ceramic industry.

Chemical Properties

White triclinic crystals or white solids. Soluble in water and decompose. Soluble in hydrochloric acid and alkali.

Uses

Zinc phosphate,monobasic is a new type of non-toxic anti-rust pigment. It can be used as the base material of various coatings such as alkyd, phenolic, epoxy resin, etc. It is also used in the production of non-toxic anti-rust pigments and water-soluble coatings. It is also used as a flame retardant for chlorinated rubber, synthetic polymer materials, and as a dental impression material.

Application

It is used as anticorrosion treatment for ferrous metal parts in the electroplating industry, and its performance is better than that of manganese dihydrogen phosphate. Also used as an anti-rust phosphating agent for metal surfaces. Used as a colorant in the ceramic industry. Used as a clarifying agent in the glass industry.

Synthesis

Zinc oxide method. Reaction equation:
2H3PO4+3ZnO→Zn3(PO4)2·2H2O+H2O
Operation method: React the diluted phosphoric acid solution with zinc oxide slurry to generate zinc phosphate, then add zinc phosphate dihydrate crystals, that is Zinc phosphate, monobasic can be obtained.
