Tabular Alumina

Tabular corundum is a pure sintered corundum that does not add any additives such as MgO, B2O3, etc., and is completely sintered and shrunk. It has a coarse and well-developed α-Al2O3 crystal structure. The content of Al2O3 is above 99%. Plate-like crystal structure, small pores and more closed pores, and the porosity is roughly the same as that of fused corundum. It has high purity, good volume stability, and extremely small reburning shrinkage. Has good thermal shock stability and flexural strength, but the price is higher than other alumina.

Quantity:
  • HH-3-6
