| 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
