HISTORY and USES

HISTORY-

  • Cobalt was discovered by Georg Brandt in Sweden
  • Cobalt was discovered in 1735
  • Bismuth, an element used to color glass deep blue, is found in the same places Cobalt is found
  • Georg tried to explain that Cobalt was being used to color glass rather than Bismuth

USES-


  • Cobalt can be alloyed with metals like Iron and Nickel to create Alnico, an alloy of unusual magnetic strength with many uses
  • Alnico is used to make jet engines, gas turbine generators, magnet steels, and stainless steels
  • Used in electroplating
  • Electroplating is a process in which one metal is plated onto another metal through means of manipulating water
  • Cobalt is used to make dark blue colors in porcelain, glass, pottery, tiles, and enamels
