Tabular corundum refractory material

Tabular corundum refractory material is alpha-alumina with sheet-shaped crystals, aluminum oxide feedstock is calcined alumina ground to a fine powder and palletized to balls with an abt diameter of 25 mm. These balls are sintered (fired) at 1750°C in modern shaft kilns and following crushed, milled, and sieved to standard fractions/sizes. Tabular corundum refractory material is a re-crystalline sintered alpha alumina with high density. It consists of large (50 – 200 µm), flat, tablet-shaped corundum crystals.
