Corundum Honeycomb Ceramic
Corundum Honeycomb
Premium-grade ceramic with >75-95% Al₂O₃ for extreme heat resistance (1400°C) and exceptional thermal shock resistance (ΔT≥300°C). Ideal for RTO systems, catalytic converters, and industrial filtration.
Key Advantages:
✔ Ultra-low thermal expansion (CTE<6)
✔ High mechanical strength (8-15MPa)
✔ Multiple cell configurations available
✔ Low water absorption (12-18%)
Applications:
• Regenerative thermal oxidizers(RTO)
• VOC abatement systems
• High-temperature catalysis
