Tabular Alumina
Tabular Alumina is a high purity sintered alumina for refractories with Aluminium Oxide(Al2O3) more than 99.8%. It's high temperature resistant, corrosion resistant, anti heat shock, tough, stable in chemical content, good in heat conductivity. After sintered, the aluminum oxide is well crystalized and has high density, low porosity and stable volume. Tabular Alumina we supply has very good particle distribution and is very clean. It's used in many process of steel making industry and also used in ceramic, metallurgical, glass industries.

Tabular Alumina: The plate-like crystal structure has small pores and many closed pores, and the porosity is roughly the same as that of fused corundum. It has high purity, good volume stability and minimal reheating shrinkage. The refractory or castable used for production has good thermal shock stability and bending strength after high-temperature treatment, but the price is higher than that of other alumina. High fire resistance; High corrosion resistance; High erosion resistance; High thermal shock stability; High strength and good toughness; Stable chemical properties. Tabular corundum is a kind of pure sintered corundum with complete shrinkage without adding any additives such as It has the characteristics of coarse crystal and good development crystal structure. The plate-like crystal structure has small pores and many closed pores, and the porosity is roughly the same as that of fused corundum. It has high purity, good volume stability and minimal reheating shrinkage.

High fire resistance; High corrosion resistance; High erosion resistance; High thermal shock stability; High strength and good toughness; Stable chemical properties. Tabular corundum is a kind of pure sintered corundum with complete shrinkage without adding any additives such as MgO and B2O3. It has the characteristics of coarse crystal and good development �±- Al2O3 crystal structure. The plate-like crystal structure has small pores and many closed pores, and the porosity is roughly the same as that of fused corundum. It has high purity, good volume stability and minimal reheating shrinkage. The refractory or castable used for production has good thermal shock stability and bending strength after high-temperature treatment Application scope of Tabular Alumina: Tabular corundum can be used as the main component in aluminum carbon, aluminum magnesium carbon, magnesium aluminum carbon, magnesium spinel and aluminum chromium refractory bricks, and can also be introduced into high aluminum amorphous refractories as enriched alumina. It can be widely used in iron and steel, casting, ceramics and other industries. Its application in iron and steel industry almost covers the whole process of ironmaking and steelmaking.
