Tabular Alumina
is a calcined alumina ceramic, sintered long enough at high temperature (1900C) to prevent shrinkage from increasing.
The result is a spherical residual porosity with large crystals of 200 to 300 um in long hexagonal tablet form (from where the adjective tabular originates).
It is found in its primary form as balls of 19 mm, crushed and as powder with a particle size always smaller than 44um.
Its properties are first those of alpha alumina with a purity of 99.8%:
Refractivity, hardness, chemical inertia, thermal connectivity and dielectric rigidity at high temperature.
It also has ceramic properties:
High density (>3.55), low open porosity, dimensional stability, creep and abrasion resistance, exceptional resistance to thermal shock, a surface coarseness which gives good bonds with the matrix, and reproducible particle size distribution.
These properties explain its development as refractory raw material, and its use in steel making and in electric furnaces, especially in Japan, as well as in ceramics, filters for molten metal, fillers for epoxy resins and polyester, inert catalyst supports and heat conductors.
