	Cobalt - Wikipedia, the free encyclopedia
		Cobalt is a central component of the vitamin cobalamin, or vitamin B-12.
		Cobalt is not found as a free metal and is generally found in the form of ores.
		Cobalt is usually not mined alone, and tends to be produced as a by-product of nickel and copper mining activities.

	Cobalt - MSN Encarta
		Cobalt melts at about 1495°C (about 2723°F), boils at about 2927°C (about 5301°F), and has a specific gravity of 8.9; the atomic weight of cobalt is 58.933.
		The chief commercial sources of cobalt are the cobaltite ores of Ontario in Canada, and the central African nations of the Democratic Republic of the Congo (DRC, formerly Zaire) and Zambia, which, along with Canada, are the world's leading producers of the metal.
		Cobalt is also used in ceramics and paint driers, and as a catalyst.

	Cobalt Info - Encyclopedia WikiWhat.com
		Metallic cobalt commonly presents a mixture of two cristallographic structures hcp and fcc with a transition temperature hcp->fcc of 722 K. Common oxidation states of cobalt include +2, and +3, though +1 is also seen.
		The isotopes of cobalt range in atomic weight from 50 amu (50-Co) to 73 amu (73-Co).

	Cobalt (Co) - Chemical properties, Health and Environmental effects
		Cobalt is used in many alloys (superalloys for parts in gas turbine aircrafr engines, corrosion resistant alloys, high-speed steels, cemented carbides), in magents and magnetic recording media, as catalysts for the petroleum and chemical industries, as drying agents for paints and inks.
		Cobalt is of relatively low abundance in the Earth's crust and in natural waters, from which it is precipitated as the highly insoluble cobalt sulfine CoS.
		Cobalt is not often freely available in the environment, but when cobalt particles are not bound to soil or sediment particles the uptake by plants and animals is higher and accumulation in plants and animals may occur.

	Cobalt (Site not responding. Last check: 2007-10-22)
		Cobalt occurs in the mineral cobaltite, smaltite, and erythrite, and is often associated with nickel, silver, lead, copper, and iron ores, from which it is most frequently obtained as a by-product.
		Cobalt is also used in other magnetic steels and stainless steels, and in alloys used in jet turbines and gas turbine generators.
		Cobalt carefully used in the form of the chloride, sulfate, acetate, or nitrate has been found effective in correcting a certain mineral deficiency disease in animals.

	Cobalt
		Reduced liver stores of cobalt are considered indicative of a dietary cobalt deficiency in ruminants (McDowell, 1992) and its measurement is generally considered sufficiently responsive to changes in cobalt intake to be of diagnostic value in cobalt deficiency (Smith, 1987).
		Cobalt has also been shown to be associated with impaired immune function in other species of ruminants, resulting in increased susceptibility to infection and reduced viability of newborn animals (MacPherson et al., 1987; Ferguson et al., 1989; Paterson and MacPherson, 1990; Fisher, 1991; Vellema et al., 1996).
