High temperature calcined alumina (α-Alumina)
High temperature calcined alumina powder is produced from industrial alumina used as raw material, at the appropriate temperature calcined into crystalline stable alpha alumina as raw material after the ball into alumina powder. It can be widely used in such as electronic equipment, structural ceramics, refractory material, wear, polishing materials, etc.
