Reaktive Gruppe	Salts, Basic
Reactivity Profile	COBALT FLUORIDE is a toxic, light brown crystalline material, when exposed to water it forms highly corrosive hydrofluoric acid. When heated to decomposition it emits toxic fumes of metallic cobalt and fluorides [Lewis, 3rd ed., 1993, p. 344].
Luftstandards	Listed as a hazardous air pollutant (HAP) generally known or suspected to cause serious health problems. The Clean Air Act, as amended in 1990, directs EPA to set standards requiring major sources to sharply reduce routine emissions of toxic pollutants. EPA is required to establish and phase in specific performance based standards for all air emission sources that emit one or more of the listed pollutants. Cobaltous fluoride is included on this list.
Air and Water Reactions	Mixes slowly with water.

Anwendungen & Verwendung

Verwenden

Cobalt(II) fluoride can be used as a catalyst to alloy metals. It is also used for optical deposition, of which it tremendously improves optical quality. The compound may be used in dental care.
