Tabular alumina is the material with high-purity alumina, without any additives for raw material. Its well-developed alpha- Al2O3 Crystal structure and crystal material within the closed pores to give a good refractoriness,high thermal shock resistance, high wear-resistance and high mechnical stability. So widely used in production, such as ladle castable, precasting blocks, sliding gate plate, purging plug, nozzles and other high-grade refractory material, etc.
