Tabular Alumina 1-3mm | Al₂O₃ 99.2% Medium Aggregate
Tabular Alumina 1-3mm medium aggregate, Al₂O₃ 99.2%, provides high packing density and hot flexural strength for high-performance castables in blast furnace troughs, EAF linings, and cement kilns.
// Key Features
- Optimized 1-3mm gradation for intermediate matrix packing in multi-fraction castables
- Closed porosity structure delivering low wettability by molten slag and metal
- High hot modulus of rupture for impact-resistant blast furnace trough linings
- Consistent grain shape and hardness reducing segregation during castable mixing
