High-alumina refractory brick is a type of aluminosilicate refractory product with an Al₂O₃ content exceeding 48%. Based on its Al₂O₃ composition, high-alumina bricks are typically classified into three grades, with grade II containing 60–75% Al₂O₃.

Performance & Advantages:

• Excellent thermal stability;

• High refractoriness;

• High refractory under load temperature;

• High resistance to erosion;

• Classified into standard, general special-shaped, special-shaped, and ultra-special-shaped bricks.

Applications:

Grade Ⅱ high-alumina bricks, leveraging their excellent high-temperature resistance and corrosion resistance, are widely used in various industrial sectors that need to withstand extreme operating conditions, such as the steel, glass, and cement industries.
