Pink Fused Alumina
It is produced by fusion of aluminum oxide and chromium oxide in electric arc furnace. Compared with white fused alumina, the addition of chromium oxide makes pink fused alumina harder.
Angular grains shape with sharp cutting edges. It is transparent pink crystal with good hydrophilicity.
