Features

Features

Monolithic α-Al₂O₃ Structure

Both fused corundum refractory brick and sintered corundum refractory brick are built from pure α-Al₂O₃, offering outstanding hardness, dimensional stability, and erosion resistance during thermal cycling.

Broad Chemical Compatibility

Thanks to the inert structure of sintered corundum refractory brick, these products resist acidic and mildly basic slags. Ideal for furnaces and kilns processing mixed or variable feedstocks.

Excellent Load Resistance at High Temperatures

All corundum refractory bricks exhibit refractoriness under load (RUL) ≥1700°C, delivering consistent shape retention and compressive strength in the hottest parts of your process.

Superior Thermal Shock and Abrasion Resistance

The dense structure of fused corundum refractory brick makes it especially durable in zones exposed to temperature fluctuations, abrasive particles, and high-velocity gas flow.
