Aluminium oxide

What is it?

Aluminium oxide (or alumina) is a chemical compound of aluminium and oxygen. Ceramic aluminium oxide at various levels of purity is the most important oxide used in ceramics.

How it is made

Aluminium oxide is usually produced industrially from bauxite, and it has numerous applications, thanks to a series of chemical and physical properties that make it suitable for a range of uses.


Aluminium oxide is the most well-known and commonly used advanced ceramic material, because it combines the basic properties of several materials of this type. It is therefore used in a large number of fields such as electronics and mechanics, and also in medicine as a material for grafts.

Aluminium oxide properties:

  • Good heat stability
  • Good resistance to corrosion
  • Does not rust
  • Excellent dielectric properties
  • Excellent hardness
  • Excellent resistance to wear
  • Excellent biocompatibility
  • Good fire resistance

Products made using aluminium oxide:

  • Components for pumps
  • Components for tubing
  • Balls for valves
  • Threaded guides
  • Mixer plates
  • Armour plating
  • Substrates and bases for resistors
  • Protective tubes for chemical processes
  • High-resistance tools
  • Cutting tools
  • Casings for thermocouples
