Alumina could be the refractory oxide of aluminum and it is located in bauxite and corundum (sapphires and rubies). It has an exceedingly high melting point.
The primary particular person to generate it was Hans Christian Oersted at Copenhagen, Denmark, in 1825, and he did it by heating aluminium chloride with potassium. Nevertheless, his sample was impure. It fell to your German chemist Friedrich Wöhler to perfect the tactic in 1827, and acquire pure aluminium for The very first time through the use of sodium in place of potassium. Glossary
