Zinc carbonate Chemical Properties,Uses,Production
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
Zinc Carbonate is used in method for producing Zinc Carbonate using electric furnace dust.
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.
