White aluminum oxide was made from the high quality alumina by melting above 2200℃ in the electric arc furnace and cooling. White aluminum oxide is white with the main crystal phase alpha-Al2O3. White aluminum oxide produced in titling electric arc furnace has the advantage of high bulk density and low porosity and the volume stability and thermal

Product Feature of White fused alumina used in ceramic line The Al2O3 purity is high(99%min). So the hardness & grinding ability is high with good grinding efficiency. High wear-resistance. Even in high-temperature circumstances, the strength is still excellent. The white fused aluminum oxide powder is suspension treated by water. So it is of flowability and

White fused alumina electrically fused in arc furnace with high grade processed alumina as raw material. It has higher hardness and slight lower toughness comparing with brown fused alumina. It is also characterized by its high purity, ability of self-sharpening, better cutting, less heat emit, higher efficiency. White fused aluminum oxide becomes the first choice for
