Cobalt Sputtering Target precipitate when aqueous solutions of cobalt(II) ions are treated with hydrogen sulfide. This reaction is useful in the purification of cobalt from its ores as well as in qualitative inorganic analysis. The sulfides of cobalt are black, semiconducting, insoluble in water, and nonstoichiometric. They react with strong acids to release hydrogen sulfide gas again. They are weak reducing agents and can be oxidized to cobalt sulfate.

Cobalt Sputtering Target three common ferromagnetic metals (iron, nickel, and cobalt), cobalt has the highest Curie point. It is unique in that, added in moderate amounts to iron, it raises that metal’s saturation magnetization. Magnetic alloys form the most important use of cobalt.

Cobalt Sputtering Target are also being tested for site specific drug delivery agents for cancer therapies and in coatings, fuel cells, batteries, DNA circuits and chrome replacement in sporting goods, luxury and consumer products.
