Aluminium oxide (Al2O3) is a chemical compound of aluminium and oxygen. Aluminium oxide is produced industrially from the mineral Bauxite. It is the most commonly occurring of several aluminium oxides and specifically identified as aluminium (III) oxide. It is commonly called alumina, and may also be called aloxide, aloxite, or alundum, depending on the forms or applications.



  • Starting material for the smelting of aluminium
  • Catalyst – carrier and adsorbent in the petroleum and chemical industries
  • Additive in paper manufacturing
  • Advanced ceramics for heavy-duty forming tools
  • Resistor-core in the Electronic Industry
  • Filler for plastics
  • Removal of water from gas streams


  • Very effective as an abrasive due to its hardness
  • Effective as a refractory material due to its high melting point
  • Very good electrical insulation
  • Very high compressive strength
  • High corrosion and wear resistance
