Aluminium Oxide

Aluminium oxide is the ceramic oxide of aluminium and, in its different purity degrees, is the most important ceramic oxide. Aluminium oxide is commonly produced by means of complex industrial processes from the mineral bauxite and its application fields are many thanks to several chemical and physical properties which make this material suitable to different purposes:

  • Good thermal stability
  • Good corrosion resistance both in acid and in alkaline environment
  • Good resistance to oxidation
  • Very good dielectric properties (electric insulator)
  • Very good hardness
  • Excellent wear resistance
  • Outstanding biocompatibility
  • Good fire resistance

Thanks to these remarkable properties aluminium oxide is employed in the electronic and mechanical field even in biomedicine as clutch material.
