Product Description

Tabular alumina is sintered in vertical kiln at ultra-high temperature with high-purity alumina as raw material, dominated by plate-like α-Al₂O₃ crystals. It features high purity, fine and uniform pores, excellent volume stability, superior thermal shock resistance, strong slag erosion resistance and high hot strength without low-melting impurities.
