text: Alumina is the common name given to aluminum oxide (Al 2 O 3 ).
text: The process involves simply re-melting the metal, which is far less expensive and energy-intensive than creating new aluminium through the electrolysis of aluminium oxide (Al 2 O 3 ), which must first be mined from bauxite ore and then refined using the Bayer process.
text: Alumina (Al 2 O 3 ), aluminium fluoride (AlF 3 ) and baked anodes are the key inputs to the smelting process; other strategic input materials include pot lining materials (cathode carbon), refractory items and steel.
text: Alumino silicate wool, also known as refractory ceramic fibre (RCF), consists of amorphous fibres produced by melting a combination of aluminum oxide (Al 2 O 3 ) and silicon dioxide (SiO 2 ), usually in a weight ratio 50:50 (see also
text: Polycrystalline wool consists of fibres that contain aluminum oxide (Al 2 O 3 ) at greater than 70 percent of the total materials and is produced by sol–gel method from aqueous spinning solutions.
text: It is a highly electropositive element and generally furnishes +3 oxidation states, as in the case of Aluminium Oxide (Al 2 O 3 ).
text: Aluminium also causes a highly beneficial hard layer of aluminium oxide (Al 2 O 3 ) to be formed on the surface that is thin, transparent and self-healing.
text: The aluminum hydroxide is then calcined to form alumina, Al 2 O 3 .
