1.Molecular Formula: ZnO 2.Molecular Weight: 81.39 3.CAS:1314-13-2 4.EINECS:215-222-5 5.Density: 5.606

       High-purity and Ultra-fine Zinc Oxide

Appearance:   white or light yellow Powder 

Melting Point: 1975 °C

Boiling Point:  2360 °C

Physical Properties:

White hexagonal system crystalloid or powder, tasteless, nontoxic, fine particle. It is amphoteric oxide, soluble in acid, NaOH, NH4CL, not soluble in water, ethanol, ammonia. It can aborb atmosphere and CO2 to generate ZnCO3, in yellow color. It turn into yellow in heating, but come back to white in cooling. Impenetrable to ultraviolet radiation, able to absorb ultraviolet radiation, no turning into black with H2S

Application:

White pigment, in dying, paper making, match, and Pharmaceuticals;

In rubber industry, it can be used as the rubber vulcanizing active agent, reinforcing agent and colorant for natural rubber and synthetic rubber.

It can be used in the making of pigment zinc chrome yellow, zinc acetate, zinc carbonate, zinc chloride;

It can be used in electron laser, phosphor powder, material additive, activator, magnetic material making
