Refractory Alumina Corundum With High Dielectric Strength Wear Resistance
Refractory Corundum Tabular Alumina
Introduction
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.
Application
Tabular alumina is the preferred aggregate for unshaped and shaped high performance refractories.
Suitable for steel, casting, cement, petrochemical, ceramics, garbage incineration and other industries.
Other common applications include electrical insulators, kiln furniture and catalyst carriers.
Flooring is an excellent product for epoxy resin or resin system filling
High dielectric strength, thermal conductivity or wear resistance required.
