Sintered Mullite Aggregate Al2O3 72% 0-1mm
Sintered Mullite Aggregate Al2O3 72% in 0-1mm grade reinforces castable microstructure with thermal shock resistance for monolithic linings in cement rotary kilns, glass tank furnaces, and steel ladles.
// Key Features
- Fine 0-1mm grading for dense monolithic lining microstructure and reduced permeability
- Low apparent porosity ≤12% for improved resistance to chemical attack
- High refractoriness supporting continuous service at 1700°C
- Consistent particle size distribution for predictable castable packing density
