Cobalt

Cobalt is a hard, lustrous, silver-gray metal that is naturally ferromagnetic and is produced via reductive smelting from chemically combined forms it is found in, in the earth’s crust. For centuries, cobalt-based blue pigments (cobalt blue) have been used in jewellery, glassware, and paints. Today, cobalt is used primarily for the manufacture of magnetic, wear-resistant and high-strength alloys. Its compounds (such as cobalt silicate or cobalt(II) aluminate) continue to be used to give the element’s distinctive deep blue colour to glass, ceramics, inks, paints, and varnishes.

Applications

  • Manufacture of magnetic and wear-resistant alloys
  • Pigments for glass, ceramics, paints and inks
  • Thin film coatings on surfaces
