Over 90% of aluminium oxide, termed smelter grade alumina (SGA), is consumed for the production of aluminium, usually by the Hall–Héroult process. The remainder, termed specialty alumina, is used in a wide variety of applications which take advantage of its inertness, temperature resistance and electrical resistance.
Aluminium Oxide (Al2O3) or alumina is one of the most versatile of refractory ceramic oxides and finds use in a wide range of applications.

Ceramic Materials. Alumina (Al 2 O 3) Widely used material with high electrical insulation and mechanical strength. Alumina was quickly adopted by the electronics field due to its high electrical insulation properties.
30 maj 2020 · Alumina is an oxide-based engineering ceramic. It can have a fairly high thermal conductivity and a moderately high heat capacity among oxide-based engineering ceramics. The properties of alumina include six common variations. This page shows summary ranges across all of them.
11 paź 2024 · Alumina, synthetically produced aluminum oxide, Al2O3, a white or nearly colourless crystalline substance that is used as a starting material for the smelting of aluminum metal. It also serves as the raw material for a broad range of advanced ceramic products and as an active agent in chemical.
17 maj 2005 · Aluminium is most commonly alloyed with copper, zinc, magnesium, silicon, manganese and lithium. Small additions of chromium, titanium, zirconium, lead, bismuth and nickel are also made and iron is invariably present in small quantities. There are over 300 wrought alloys with 50 in common use.
