The highest demands of high bend strength thermal shock resistance resistance to acid and alkali conditions abrasion and wear resistance requires the qualities of 99 Al2O3 ceramics. The ceramic bodies can be used by an addition of approximately 25 water for slip casting or even as an extrusion mix by addition of a suitable plasticizer.
