Description

Corundum Bricks Introduce

Corundum bricks are refractory bricks with corundum as the primary crystalline phase, containing over 95% alumina (Al₂O₃). They are primarily manufactured from industrial alumina or high-grade bauxite through high-temperature sintering.

Our high-purity corundum bricks can withstand service temperatures exceeding 1770°C. They feature excellent thermal shock resistance, maintaining structural stability even under rapid temperature fluctuations.

Advantages of Corundum Bricks

Excellent Thermal Shock Resistance

Highly suitable for environments with frequent and rapid temperature fluctuations.

Superior Chemical Stability

Corundum bricks offer outstanding corrosion resistance and can withstand the attack of various chemicals.

High Mechanical Strength and Abrasion Resistance

Resistant to corrosion and wear, ensuring stable and reliable performance.
