AluChem AC-99 Tabular Aluminas are high-density, fully shrunk, coarse crystalline alpha aluminas that have been converted to the corundum form. Tabular Alumina is produced by sintering ball-formed calcined alumina at a temperature just under the 2040°C fusion point of aluminum oxide. These Tabular Alumina balls are then crushed, graded or screened, and ground to a wide range of granular or powdered particle size distributions.
The typical chemical and physical properties which characterize AluChem’s AC-99 Tabular Aluminas are presented in this product data. Some of these properties are highlighted by the following:
