Cobalt(II) fluoride Chemical Properties,Uses,Production

Preparation

Cobalt(II) fluoride is prepared by heating anhydrous cobalt(II) chloride or oxide in a stream of hydrogen fluoride:
CoCl2 + 2HF → CoF2 + 2HCl
CoO + 2HF → CoF2 + 2H2O
Also, cobalt(II) fluoride can be prepared as a tetrahydrate, CoF2•4H2O by dissolving cobalt(II) hydroxide in hydrofluoric acid. The tetrahydrate is then dehydrated to anhydrous fluoride. Elemental fluorine combines with cobalt at 450°C forming mixtures of cobalt(II)–and cobalt(III) fluorides.

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. Tetrahydrate is red orthogonal crystal; density 2.22 g/cm3; decomposes on heating; soluble in water; di- and trihydrates are soluble in water.

Uses

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.

Uses

Catalyst for organic reactions.

General Description

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

Reactivity Profile

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

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.
LD50 oral (rat): 150 mg/kg

Safety Profile

Poison by ingestion. When heated to decomposition it emits toxic fumes of Co and F-.
