Tabular Alumina
Tabular Alumina is made of high-purity alumina, which is pure, sintered corundum that has been fired and shrunk completely without adding any additives. It has high fire resistance, excellent thermal shock resistance, creep and spalling resistance, as well as high purity and good volume stability. It could be widely used in steel, casting, ceramics and other industries.
