Alumina raw materials

Zirconia is produced by calcining zirconium compounds, exploiting its high thermal stability.

The main use of zirconia is in the production of ceramics, with other uses including as a protective coating on particles of titanium dioxide pigments, as a refractory material, in insulation, abrasives and enamels.

  • Use temperatures up to 1500℃
  • Low thermal conductivity
  • Chemical inertness
  • Wear resistance
