99.2% Al2O3 Tabular Corundum / Tabular Alundum Crystal High Fire Resistance
99.2% Tabular Alumina / Al2O3 / Tabular Corundum / Tabular Alundum
Product Introduction
Tabular Alumina is a pure sintered α -alumina material that is fully densified by rapid sintering at temperatures in excess of 1900°C without the use of sintering AIDS.
The tabular alumina is characterized by large and developed hexagonal sheet α -alumina crystals. Its excellent thermal volume stability and thermal shock properties are attributed to its special microstructure: low open porosity and large crystals, which form closed spherical pores when recrystallized during rapid sintering.
Advantages
Excellent thermal volume stability and thermal shock
Excellent dielectric properties
High fire resistance
High mechanical strength
Good chemical purity
Good acid and alkali corrosion resistance
