Calcined fused alumina

Product characteristics

Calcined fused alumina is obtained by regular calcination of brown fused alumina at high temperature until a blue color of grain is obtained. This process enables to remove cracks on the surface and inside the crystals and then improves a lifetime of grain. The property of calcined fused alumina enhances the self-sharpening characteristic.
