White Aluminum Oxide F12 F14 F16
White aluminum oxide using high quality alumina powder as raw
material, by refining and crystallizing in electric arc furnace with high temperature. It has white color, slightly harder and lower toughness comparing with brown fused alumina. Its micro hardness is 2200-2300kg/mm². With high purity, better self-sharpening and grinding ability, good acid and caustic corrosion resistance, high temperature resistance and good thermal stability.
