Corundum Dense Castable Al2O3 95%
Corundum dense castable Al2O3 95% for gasifiers, coal injection lances, and highest-demand industrial applications. Extreme refractoriness, maximum density, and superior resistance to molten slag and reducing atmospheres.
// Key Features
- High refractoriness to 1850°C based on pure corundum aggregate
- Maximum bulk density (≥3.00 g/cm³) for near-zero infiltration porosity
- Exceptional resistance to reducing atmospheres, H2S, and CO environments
- Superior slag resistance against iron, alkali, and acidic oxide attack
