Tabular Alumina 3-5mm | Al₂O₃ 99.2% Coarse Aggregate
Tabular Alumina 3-5mm coarse aggregate, Al₂O₃ 99.2%, maximizes grain interlocking and hot strength in dense refractory castables for steel ladle walls, EAF upper shells, and glass furnace regenerators.
// Key Features
- Coarse 3-5mm grains forming load-bearing skeleton in dense castable matrices
- Excellent thermal shock resistance due to uniform α-Al₂O₃ corundum microstructure
- Superior slag penetration resistance in steel ladle and EAF applications
- Low reversible thermal expansion reducing lining stress during thermal cycling
