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.
Contents
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
Zinc phosphate does not require special disposal and poses no toxicity for the environment. It can be safely dumped in the ground.
