Umicore Cobalt & Energy products, with its plants in Belgium (Olen) and South-Africa (Roodepoort), is by far the largest cobalt oxide manufacturer world-wide. With a unique production process , Umicore is able to manufacture the most consistent and highest quality available on the market. As such, it is no surprise that Umicore's quality is THE reference in the ceramic pigment-industry whether it be in Japan, the Far East, Europe or the Americas.

Cobalt oxide qualities :

  • Standard Black Oxide OR, typically 71,5 % Co content
  • Standard Black Oxide EX, typically 73,5 % Co content
  • Grey Oxide, typically 75,5 % Co content
  • Cobalt Oxide Ceramic Grade, typically 73 % Co content
  • Cobalt Oxide GCQ, typically 68 % Co content
  • Cobalt Oxide Special Grade, typically 56 % Co content

Highly stable physical properties together with low and consistent impurity levels (in particular sodium) have led to the Umicore “EX” and “GO” grades as being the preferred cobalt oxide for most producers of electronic components. Typical applications are thermistors or for magnet materials. The chemical industry is also extensively using cobalt oxide as a catalyst.

Umicore's quality guarantee and commitment are guarantees for its success.
