Cobalt blue is a blue pigment made by sintering cobalt(II) oxide with aluminium(III) oxide (alumina) at 1200 °C. Chemically, cobalt blue pigment is cobalt(II) oxide-aluminium oxide, or cobalt(II) aluminate, CoAl 2 O 4. Cobalt blue is lighter and less intense than the (iron-cyanide based) pigment Prussian blue.
Cobalt is an essential element for health in animals in minute amounts as a component of vitamin B 12. A deficiency of cobalt, which is very rare, is also potentially lethal, leading to pernicious anemia. [1] Exposure to cobalt metal dust is most common in the fabrication of tungsten carbide. [2]

The Curie temperature is 1,115 °C (2,039 °F) [12] and the magnetic moment is 1.6–1.7 Bohr magnetons per atom. [13] Cobalt has a relative permeability two-thirds that of iron. [14] Metallic cobalt occurs as two crystallographic structures: hcp and fcc. The ideal transition temperature between the hcp and fcc structures is 450 °C (842 °F ...
