Zinc Oxide
Molecular formula:ZnO
Executive Standard:GB/T 3185-92
Description: Zinc Oxide is a hexagon crystals or white powder. It has relative density of 5.41~5.67, melting point of 1975C°and 1800 C°sublimation. It is yellow at high temperature, back to white after cold. The refractive index is 2.0041. Soluble in acid, alkali metal hydroxide, ammona, ammonium carbonate and ammonium chloride solution. Hard to dissolve in water and alcohol. It's none toxic and odourless. Can abosrbs CO2 and water.
