Spherical alumina is basically alumina “shaped” in a high temperature fusion process. Spherical alumina therefore has the same intrinsic properties as any other alumina. Its chemical formula is Al 2 O 3. At Sibelco high purity aluminas are being used to make
Spherical Alumina is used in resins, rubbers & plastics as fillers for thermal conductive sheets, fillers for molding materials, and more. GNP Graystar ’s Spherical Alumina is a spherical alumina powder with high thermal conductivity, good heat resistance, high electrical insulation, high …
White-Fused Aluminum Oxide is electrically fused in an arc furnace using Bayer process high purity alumina. The final product is used in appliions where higher purity levels and lower iron content is desired as compared to Brown-Fused Aluminum Oxide. GNP Graystar ’s White Aluminum Oxide is used in refractories, thermal coatings, and other appliions requiring a raw material with high
