Product Description

Product Description

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. Tabular alumina has high heat resistance, mechanical strength, abrasion resistance, high chemical purity, excellent insulation properties, acid and alkali corrosion resistance.
