Product Description
Calcined Alumina
CAS No.:1344-28-1
Chemical Formula: Al2O3
M.Wt: 101.94
S.Gravity: 3.4〜4.0
Purity: 99.5％min.
Appearance: White crystalline powder
Calcined (or alpha) alumina is made by roasting a source alumina powder at 1200-1300C to convert it to pure Al2O3 (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. It is insoluble in water but is soluble in hydrofluoric acid and potassium bisulfate. Unground calcined aluminas are typically 100-300 mesh, but much finer grades (often called "Ground Alumina") are produced by milling. Calcined aluminas are available in numerous grades based on the heat treatment applied, crystal size, soda content, and degree of thermal conversion to alpha phase. Soda content is a major factor in determining the final use (low soda materials are used for electronic applications, medium soda for electrical insulation and porcelains, high soda for glass, glaze, fiberglass and electrical porcelain).
Calcined Alumina Application:
• High temperature refractories
• Electronic devices
• High alumina porcelain parts
• Wear-resistant Porcelain Parts
