Tabular Corundum is high-density, fully shrunk, coarse crystalline alpha alumina that has been converted to the corundum form. It is a completely recrystallized α-alumina sintered at slightly below the melting point of imported alumina after batching, grinding and molding.
Tabular Corundum 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. Tabular corundum has characteristic large, well developed hexagonal tablet shaped α-alumina crystals of up to 200μm length.
Tabular Corundum is the preferred aggregate of amorphous and shaped high performance refractory materials, widely used in steel, casting, petrochemical, ceramics and incineration industries as well as electrical insulation, kiln furniture and catalyst carriers. Finely ground tabular alumina powder is an excellent product that used as a filler in epoxy resins or resin systems. It is used to obtain the desired high dielectric strength, thermal conductivity and wear resistance.
