Brown fused alumina

Brown fused alumina consists almost entirely of aluminium oxide and is almost iron-free. Brown fused alumina is less pure than white fused alumina. The special composition of this angular mineral makes it extremely stable. It is also both hard and tough. Brown fused alumina is primarily used as a blasting medium and in floorings. It belongs to the group of fused alumina.
