MATERIAL OVERVIEW

Characteristics: Steel-gray, shining, hard, ductile, somewhat malleable metal; ferromagnetic, with permeability two-thirds that of iron.  Cobalt has exceptional magnetic properties in alloys.   It is attached by dilute hydrochloric and sulfuric acids.  It is soluble in nitric acid.  Cobalt corrodes readily in air.  Hardness: cast, 124 Brinell; electrodeposited, 300 Brinell.  An important trace element in soils and necessary for animal nutrition.  Cobalt has unusual coordinating properties, especially the trivalent ion.  Noncombustible except in powder form.

Derivation: From ore concentrates by roasting followed (a) by thermal reduction by Cobalt, or (b) by electrolytic reduction of solutions of metal; (c) by leaching, with either ammonia or acid in an autoclave under elevated temperatures and pressures and subsequent reduction by H.

Hazard:  Dust is flammable and toxic by inhalation.  Tolerance, 0.05mg/m³ of air.
