We are supplier and exporter of Calcined Alumina. Calcined alumina can be used in the polishing of different alumina products(mainly used in middle, fine polishing).It is also widely used in high-class aluminium refractory material, unshaped refractory materials, high aluminium ceramic product and advanced coating, etc, . Item Al2o3 % Na2o % Sio2 % Fe2o3 % D50 A4m 99.8 0.1 0.05 0.02 3.1 Alumina (Al2O3), the industrial Al2O3 is prepared from alumina (Al2O3, 3H2O) and hard alumina, and the Al2O3, which is high in purity, is usually prepared by chemical methods. Al2O3 has many isomorphic crystals, and there are currently more than 10 known types, mainly three types of crystal, namely gamma-al2o3, beta-al2o3, alpha-al2o3.Which structure is different, with different properties in high temperature above 1300 s almost entirely into alpha Al2O3.
Brown aluminum oxide is made by high quality bauxite as main material, fusing and purifying in a pouring electric arc furnace at a temperature of over 2200C, and made into different grain sizes through crystal, choosing, crashing, magnetic, separating, screening, washing etc. It is characterized by its high hardness, good toughness and sharp shape in particles. Brown Fused Alumina(BFA) is made from Calcined Bauxite. It is a hard and tough material, used in manufacturing of grinding wheels (both vitrified and resin bonded) and coated products. These grains are also used for shot blasting and as polishing Media. Refractory grade BFA is used as a raw material in the manufacture of high Alumina refractory. It is available in grit sizes as per FEPA for abrasive applications and group grits for refractory applications.
