White Aluminum Oxide
High-purity white fused alumina with sharp edges and superior thermal stability.
White Aluminum Oxide is fused from high-purity alumina powder in an electric arc furnace at very high temperatures. It has brilliant white color, extraordinary hardness and sharp edges; high corrosion resistance; and excellent volume stability and thermal shock resistance thanks to high bulk density and low porosity.
