Zinc Powder
Synonyms: Zinc Powder
CAS NO. 7440-66-6
Molecular Formula: Zn
Molecular Weight: 65.38
Properties: gray metallic fine powder, density 7.14g/cm3, melting point 419oC boiling point 907oC, dissolving in acid, alkali and ammonia water but not in water. It has strong reducibility and adhesive power. It remains stable in dry air, but tends to agglomerate in moist air and results in alkaline carbonate on the surface of the particles.
Usage: Superfine zinc powder is mainly used as key raw material in zinc-rich coating,as well as in anti-corrosion, environment protection and other high performance coating. They can be widely applied in large steel structures, ship building, container industries aviation, automobile, Ordinary zinc powder can be widely applied in metallurgy,chemical industry,pharmacy,dye,battery and other areas.
Packing: Packed in iron drums with plastic bags,50kg per drums,or as requested by the clients.
