Hazard Information

General Description

Violet to red solid. Sinks and mixes slowly with water.

Reactivity Profile

COBALT FLUORIDE(10026-17-2) is a toxic, light brown crystalline material, when exposed to water COBALT FLUORIDE(10026-17-2) forms highly corrosive hydrofluoric acid. When heated to decomposition COBALT FLUORIDE(10026-17-2) emits toxic fumes of metallic cobalt and fluorides [Lewis, 3rd ed., 1993, p. 344].

Air & Water Reactions

Mixes slowly with water.

Hazard

Highly toxic.

Health Hazard

INHALATION: Inhalation of dust may cause pulmonary symptoms. EYES: Irritation. SKIN: Skin rashes, dermatitis. INGESTION: Nausea and vomiting caused by local irritation.

Chemical Properties

Rose-red crystals or powder. Soluble in cold water and hydrofluoric acid. Decomposes in hot water. Ammine complexes can be prepared from the hydrate.

Physical properties

Red tetragonal crystal; density 4.46 g/cm³; melts at 1,127°C; vaporizes around 1,400°C; sparingly soluble in water; soluble in warm mineral acids; decomposes in boiling water.
