Calcined Alumina - Digitalfire
Calcined (or alpha) alumina is made by roasting a source alumina powder at 1200-1300C to convert it to pure Al 2 O 3 (when calcined near 2000C large hexagonal, elongated tablet shaped crystals form as "Tabular Alumina"). The alpha form is the densest and most stable crystalline form of alumina.
