Refractory Sintered White Tabular Alumina Al2O3 6mm 3mm 99.5% For Steel Ladles
Refractory Raw Material Sintered White Tabular Alumina 6-3mm 99.5% for Steel Ladles
1. Tabular Alumina Introduction
Tabular alumina is produced by sintering ball-formed calcined alumina at the temperatures around 1800°C. The alumina is formed from pure aluminum oxide. Practically all porosity and shrinkage is removed under such high temperature. Essentially tabular alumina is 100 percent alpha alumina.
These tabular alumina balls are then crushed, graded or screened, and ground to a wide range of granular or powdered particle-size distributions. Tabular Alumina can appear as white crystalline granules or powder. It is available as low soda, de-ironed and de-dusted and in a wide variety of sizes.
