Aluminium Oxide

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 particular forms or applications.

Usage

  • Used as a starting material for the smelting of aluminium
  • Used as catalyst carrier and adsorbent in the petroleum and chemical industries
  • Used as an additive for paper manufacture
  • Used in advanced ceramics for heavy-duty forming tools
  • Used as resistor core in the Electronic Industry
  • Used as filler for plastics
  • Used to remove water from gas streams

Benefits

  • 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
