Product Description
Calcined Bauxite
Alumina hollow bricks are a type of high-performance refractory material, extensively used in high-temperature industries such as
steel, glass, ceramics, petrochemicals, and environmental protection sectors. Renowned for their exceptional thermal stability and
excellent insulation properties, these bricks offer a comprehensive profile of features and applications outlined below:
Product Description:
1. Composition: Alumina hollow bricks are primarily fabricated from high-grade alumina (Al2O3) materials, with alumina content
ranging between 75% to 99%, tailored to varying application requirements. The internal hollow structure not only reduces
self-weight but also enhances the thermal insulation efficiency.

2. High-Temperature Performance: They exhibit outstanding stability under extreme heat, maintaining structural integrity over
prolonged exposure to high temperatures, with a resistance capability exceeding 1750°C, making them suitable for harsh thermal
processing environments.

3. Low Thermal Conductivity: The hollow design minimizes heat conduction, effectively blocking heat transfer, reducing energy
consumption, and boosting the thermal efficiency of furnaces and other equipment.

4. Corrosion Resistance: Alumina-based materials demonstrate strong resistance against various chemical corrosions, particularly
excelling in alkaline or neutral atmospheres, ideal for environments exposed to molten metals, glass melts, and other
corrosive media.

5. Mechanical Strength: While lightweight, they retain a commendable compressive strength and flexural strength, ensuring minimal
risk of damage during installation and service.

6. Dimensional Precision and Installation Convenience: Precisely engineered, they offer accurate dimensions, facilitating easy
on-site installation and compatibility with complex structural designs.
