ZINC SILICOFLUORIDE

Chemical properties

White crystals.Decomposes on heating; soluble in water.

General Description

A solid material, or the solid mixed with water. Insoluble in water and denser than water. Contact with the material may cause irritation to skin, eyes, and mucous membranes. ZINC SILICOFLUORIDE may be toxic by ingestion.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

ZINC SILICOFLUORIDE has weak oxidizing or reducing powers. Redox reactions can however still occur. The majority of compounds in this class are slightly soluble or insoluble in water. If soluble in water, then the solutions are usually neither strongly acidic nor strongly basic. These compounds are not water-reactive.

Health Hazard

Inhalation of dust irritates nose and throat; excessive inhalation may cause severe pulmonary inflammation. Ingestion causes nausea, cramps, vomiting, shock, convulsions, cyanosis, and other symptoms of fluoride poisoning. Contact with eyes or skin causes irritation; skin ulcers may develop.

Fire Hazard

Special Hazards of Combustion Products: Toxic and irritating hydrogen fluoride and silicon tetrafluoride are formed in fires.

Safety Profile

Poison by ingestion and subcutaneous routes. When heated to decomposition it emits toxic fumes of F- and ZnO. See also ZINC COMPOUNDS.
