| Hazard Information | Back Directory | [Chemical Properties]
White, crystalline powder. Evolves carbon dioxide at 300C. Soluble in acids,
alkalies, and ammonium salt solutions; insoluble in
water. | [Uses]
Antiseptic (topical); astringent. | [General Description]
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. | [Reactivity Profile]
ZINC CARBONATE(3486-35-9) reacts with acids to generate carbon dioxide and a zinc-containing solution. Dissolves in bases and in solutions of ammonium salts. | [Air & Water Reactions]

| Questions And Answer | Back Directory | [Physical Properties]
White crystalline solid; orthorhombic structure; refractive index 1.818; Mohs hardness 4.3; decomposes at 300°C forming zinc oxide; practically insoluble in water, 10 mg/L at 15°C; soluble in acids, alkalis, and ammonium salt solutions.
| [Occurrence and Uses]
Zinc carbonate occurs in nature as mineral smithsonite and zincspar. The compound is used in ceramics and fire proofing filler for rubber and plastics.Also, it is used in lotions, ointments, cosmetics, and as a topical antiseptic.
| [Production]
Zinc carbonate is derived from its mineral smithsonite. Also, the compound may be prepared by the reaction of sodium bicarbonate with a soluble zinc salt:
ZnCl2 + NaHCO3 → ZnCO3 + NaCl + HCl
