AZS Fused Cast Brick ZrO2 36% (AZS 36#)
AZS 36# premium fused cast brick with ZrO2 36% for glass furnace throat and breast wall. Elevated zirconia content reduces exudation phase and glass contamination risk in float glass, E-glass, and optical glass furnaces.
// Key Features
- Premium glass melt corrosion resistance exceeding AZS 33# grade
- Ultra-low porosity (<1%) preventing glass inclusion defects
- Reduced exudation phase minimizing downstream glass contamination
- Enhanced structural integrity at glass furnace throat operating temperatures
