Detailed Product Description:

Refractory grade tabular alumina TA for firebricks

 Tabular alumina is a purely sintered αcorundum material that is a compact body rapidly sintered at temperatures above 1900 ° C without sintering aids. Tabular alumina has approximately 200 μm and well-developed hexagonal plate-like α-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.
