AKA: 3486-35-9, Zinc monocarbonate, Zincspar, Carbonic acid, Zinc salt (1:1), Natural smithsonite, Zinc carbonate (1:1), CI 77950, C.I. 77950
Synthetic
Clean
OriginSynthesized from zinc oxide and carbon dioxide through chemical reaction in controlled industrial conditions. Produced via carbonation process where zinc compounds are exposed to CO₂ gas to form the carbonate salt.
Zinc carbonate appears as a white crystalline solid or powder that is insoluble in water. The primary hazard is the threat posed to the environment. Immediate steps should be taken to limit its spread to the environment. Used in pharmaceuticals, to make other zinc compounds, as a feed additive.
Solubility 0.001 G/100 G OF WATER AT 15 °C; SOL IN DIL ACIDS, ALKALIES & SOLN OF AMMONIUM SALTS.
