Fused α-β Alumina Bricks

Fused α-β Alumina Bricks are manufactured using high-purity alumina raw materials through a specialized electric melting process. Their unique crystal structure and chemical composition confer exceptional performance characteristics:

Superior high-temperature resistance: The α-β corundum phase structure ensures stable physical and chemical properties at elevated temperatures。

Excellent resistance to glass vapor erosion: Exceptional resilience against alkaline vapors and glass volatiles。

Outstanding thermal shock stability: Unique thermal expansion characteristics enable withstanding frequent temperature fluctuations。

Low thermal conductivity: Effectively reduces kiln heat loss and enhances energy efficiency。

Typical Physical and Chemical Properties:

Al₂O₃ Content: ≥93%

Bulk Density: ≥3.20 g/cm³

Apparent Porosity: ≤5%

Room-temperature compressive strength: ≥150 MPa

Maximum operating temperature: ≥1700°C

Fused α-β Alumina Bricks are widely used in the following high-temperature industrial equipment:

1. Upper structures of glass melting furnaces: large arches, breast walls, front walls, small furnaces, etc.

2. Ceramic kilns: Lining materials for high-end sanitaryware and tableware kilns.

3. Chemical kilns: Lining for petrochemical catalytic cracking units.

4. Metallurgical industry: Thermal processing equipment such as heating furnaces and heat treatment furnaces.

5. Electronic materials kilns: Lining materials for electronic ceramic sintering kilns.
