Brown Aluminum Oxide

Brown Aluminum Oxide is produced by smelting calcined bauxite in an electric arc furnace at temperatures greater than 2000℃. A slow solidification process follows the fusion to yield blocky crystals. The melting helps in removing residual sulfur and carbon. Strict control during the fusion process ensures optimum toughness of the grains. Brown aluminum oxide is characterized by high purity, good crystal, strong fluidity, low linear expansion coefficient, and good corrosion resistance.
