CerTab - Tabular Alumina and CerTab LS

CerTAB
Tabular Alumina and CerTab LS

A high quality shaft-kiln produced tabular alumina, processed in the UK to ensure total logistical and quality control. Extensive use in the production of steel, glass and ceramic refractories. Low iron version available for technical ceramics and aerospace applications. CerTab LS is a low sodium (Na₂O) content alumina.

Produced from high temperature sintering of Bayer process calcined alumina.

Major phase identified by X-Ray Diffraction as massive corundum. CerTab ensures complete control of the chemistry and physical properties promoting complete control of the final ceramic system.
