China Factory Export Basic Zinc Carbonate 57.5%
China Factory export Basic Zinc Carbonate 57.5%
Zinc carbonate, fine white amorphous powder, odorless. The main component of calamine and secondary minerals formed in the weathering or oxidation of zinc ore belt, is sometimes substituted carbonate rock may constitute zinc ore. Used as a zinc carbonate light astringent, calamine, skin protective agent, raw latex products.
Alias: bonamite
English alias: carbonuredezinc; zincmonocarbonate; Zinkcarbonat; zincspar; smithsonite;
CAS: 3486-35-9
Molecular formula: C2H8O13Zn5
Properties: white or yellowish fine amorphous powder, smell-less, tasteless. The proportion is 4.42-4.45, does not dissolve in water and alcohol, slightly soluble in ammonia, can dissolve in the diluted acid and the sodium hydroxide.
Main Application:
In pharmaceutical, used as a skin protector, or Preparation of calamine lotion; in Feed, it is Zinc supplements.Â
In industrial application, it is used as Light astringent, raw material in Rayon production,Desulfurizer in fertilizer production, Raw materials in Catalyst production, and widely applied in Rubber industries, paint and other chemical industries. In oil drilling, Zinc carbonate can be used as Corrosion inhibitors, sulfur removal agent in Oil and gas wells to react with H2S to get a stable/insoluble ZnS to get rid of the pollution and corrosion of H2S.
