Refractory Artificial Corundum Tabular Alumina 99.2% Pure Sintered Alpha Alumina Material
Refractory Artificial Corundum Tabular Alumina
Introduction
Tabular Alumina is a pure sintered alpha-alumina material that has been fully densified by rapid-sintering without the use of sintering aids at temperatures in excess of 1900°C.
Tabular Alumina has characteristic large, well developed hexagonal tablet shaped alpha-alumina crystals. The excellent thermal volume stability and thermal shock characteristics can be attributed to its specific microstructure: low open porosity and large crystals with closed spherical pores,which are entrapped upon re-crystallization during rapid sintering.
Advantages
Suitable for steel, casting, cement, petrochemical, ceramics, waste incineration and other industries.
Other common applications include electrical insulators, kiln fixtures and catalyst supports.
Floor is an excellent product, can be used for epoxy resin or resin system filling
High dielectric strength, thermal conductivity or wear resistance is required.
