Tabular Alumina Balls
Tabular alumina balls 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 3704°F (2040°C) fusion point of aluminium 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 tabular aluminas are presented in this product data.
• Good resistance to thermal and mechanical shock
• Excellent abrasion resistance
• White crystalline granules or powder
• Depending on requirements, ball sizes are produced from 1/8 to 1 inch (tolerance ± 1 mm)
• Regenerative burner bed applications
• Deep bed molten aluminium filtration
• Heat exchange media
