Zinc phosphate is an inorganic chemical compound with the molecular formula Zn3(PO4)2, used as a corrosion resistant coating on metal surfaces and in special cements.

Properties

Chemical

Zinc phosphate reacts with strong acids to release phosphoric acid.

Physical

Zinc phosphate is an odorless white crystalline solid, practically insoluble in water (0.03 g/l), which melts at 900 °C.

Availability

Zinc phosphate is sold by chemical suppliers.

Preparation

Zinc phosphate can be prepared by reacting phosphoric acid with zinc oxide. The reaction is exothermic and should be performed in a cooled container or glass slab.[1]

Projects

  • Make dental cement

Handling

Safety

Powdered zinc phosphate may cause eye or skin irritations, especially the anhydrous form. It should not be consumed as a zinc and phosphorus supplement.

Storage

In closed bottles, away from moisture.

Disposal
