Description
Tabular Alumina is a high-density, fully shrunk, coarse crystalline alpha-alumina that has been converted to the corundum form. It is a completely crystallized α-alumina sintered at slightly below the melting point of imported alumina after batching, grinding, and molding.
Tabular Alumina is produced by sintering ball-formed alumina at a temperature under the 2040°C fusion point of aluminum oxide. The crystals are arranged in a tabular staggered way, which increases the mechanical strength of the particles.
