White Tabular alumina/Tabular corundum/99.2%Al2O3 Tabular aluminum/alumina

 

Production: white tabular alumina

Tabular alumina is a purely sintered corundum material that is a compact body rapidly sintered at temperatures above 1900 C without sintering aids. Tabular alumina has approximately 200 m and well-developed hexagonal plate-like -corundum crystals. Its excellent thermal volume stability and thermal shock resistance can be attributed to the following special microstructure of platy corundum: less open pores, large crystals, closed spherical pores due to recrystallization trap during rapid sintering.
