Product Description
High Purity Good Sintering Alpha Calcined Alumina Powder for Ceramic Roller and Polishing
Product name:calcined alumina
CAS NO. : 1344-28-1
EINECS No.:215-691-6
Molecular Weight:101.96
HS Code:2818109000
Molecular Formula: Al2O3
Melting point:2054ºC
Water solubility: insoluble in water, soluble in strong alkali and strong acid

Properties:
Calcined alumina is produced through the calcination (“heating”) of alumina to various temperatures. By controlling the
calcination temperatures and time, the properties of the alumina can be controlled. Calcined alumina is therefore utilized in a variety of industrial applications including Structural ceramics, Technical ceramics, Polishing compounds for plastic, metal, and glass, Fillers for Rubber and Plastics, Friction - anti slip, Refractories, Paint & Coatings and Thermal Spray Powders.
