Tabular alumina 0-200um 0-250um 0-500um refractory sand

Tabular alumina 0-200um 0-250um 0-500um refractory sand

BRIEF DESCRIPTION
Tabular alumina is a kind of pure sintered corundum,which is sintered and completely
shrink without adding any additive,such as MgO or B2O3,with coarse crystals and
well developed Al2O3 crystal structure.The tabular crystal structure is characterized
by narrow pores,with more closed porosity, almost the same apparent porosity
compare with fused corundum ,high purity, good stability volume density,tiny refiring
shrink.After high temperature treatment,tabular alumina is used for refractories and
castable characterized by good thermal shock stability and flexural strength.
