Tabular alumina balls are high-density, fully shrunk, coarse crystalline alpha alumina converted to corundum form. These items are produced by sintering ball-formed calcined alumina at a temperature just below aluminium oxide's 2040°C (3704°F) fusion point. The tabular alumina balls are graded or screened, and then crushed or ground
