Zinc phosphate

(CAS: 7779-90-0)

Product features:
Zinc Phosphate is a white powder, molecular formula is Zn3(PO4)2, average molecular weight is 386.11.
It is easily deliquescence, insoluble in water. The apparent density is 0.8 - 1g/cm3. Soluble in inorganic acid, sodium hydroxide, ammonia, ammonium salt solution. Insoluble in water and ethanol. Easily soluble in mineral acid and sodium hydroxide solution. When heated to 100℃, it loses 2 crystal water and becomes anhydrous. Deliquescence. Zinc phosphate is a white non-toxic and pollution-free anti-rust pigment. It can effectively replace the traditional anti-rust pigments containing heavy metal lead and chromium. It is a new anti-rust pigment product with ideal use effect. Zinc phosphate has a strong complexing ability to trivalent iron ions. Phosphate ions react with the iron anode to form a complex protective film with iron phosphate as the main body. This dense purification membrane is insoluble in water, has high hardness, excellent adhesion, and exhibits excellent anti-rust performance. Because the zinc phosphate gene has good activity, it can react with many metal ions to form complexes. Therefore, it has a good anti-rust effect.
