Zinc carbonate Chemical Properties,Uses,Production

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

Chemical Properties

White, crystalline powder. Evolves carbon dioxide at 300C. Soluble in acids, alkalies, and ammonium salt solutions; insoluble in water.

Chemical Properties

Smithsonite is zinc carbonate, ZnCO3, a hexagonal mineral with a rhombohedral cleavage. It is a brittle mineral; hardness, 4–4.5; specific gravity, 4.3–4.5; luster, vitreous to dull; color, usually white, but may be colored yellowish or brownish or perhaps blue or green due to impurities. It is translucent to opaque.

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 reacts with acids to generate carbon dioxide and a zinc-containing solution. Dissolves in bases and in solutions of ammonium salts.

Health Hazard

INHALATION OF DUST OR FUMES: Dry throat, cough and chest discomfort. Fever and sweating. SKIN: Astringent. INGESTION: May cause nausea and vomiting.

Fire Hazard

Behavior in Fire: Could decompose to liberate CO 2

Safety Profile

An experimental teratogen. When heated to decomposition it emits toxic fumes of CO and Zn.
