Tabular Alumina Introduction

Tabular alumina is a purely sintered α-corundum 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.


Features

1. low open porasity and large crystals with closed spherical pores

2. extremely high refractoriness, high mechanical strength and abrasion resistance

3. good chemical purity, excellent dielectric properties and good resistance against acid and alkali corrosion.
