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.
