Tabular Alumina is an aggregate of high-purity, well-sintered ( ≥ 1900℃) crystalline alpha alumina, it has coarse crystal, well-developed a-Al2O3 crystal structure . Tabular Alumina has high temperature volume stability, low water absorption, low apparent porosity and impurities, and high thermal thock resistance. Tabular Alumina can be used as the main component in aluminium-carbon, widely apply to the steel, casting, ceramics etc., its application in iron and steel industry almost covers.
