Brown Fused Aluminium Oxide （A）

A-type brown fused alumina is made from high-quality bauxite by fusing in a pouring electric arc furnace at a high temperature above 2000℃.  Crushed and dressed with an aero-fall mill and followed by magnetic-separating and screening, the crystallized ingot becomes grains of dense structure, great hardness, good self-sharpening and excellent grinding properties.  And the grains are in blocky shape.  A-type brown fused alumina is suitable for manufacturing vitrified and resinoid tools, and for lapping, polishing and blasting. It may also be used as superior refractories.
