Product Description of Beta Alumina Refractory Bricks For Glass Furnaces

Fused Alumina Bricks (Beta Alumina Bricks) are primarily composed of the β-Al₂O₃ crystalline phase, with a content of approximately 50%. These bricks have a dense crystalline structure and exhibit excellent corrosion resistance to molten glass at temperatures below 1350°C. As a result, they are widely used in the working pool and rear sections of glass furnaces. Common applications include flow channels, lip bricks, and gate bricks.

Due to the saturation of Al₂O₃ by sodium above 2000°C, beta alumina bricks demonstrate exceptional stability against alkali vapors at high temperatures. Additionally, their thermal shock resistance is among the best of fused cast bricks. However, when in contact with SiO₂, the Na₂O in beta alumina bricks reacts with SiO₂, causing β-Al₂O₃ to convert to α-Al₂O₃, which results in significant volume shrinkage. This may lead to cracks and damage to the bricks. Therefore, these bricks are only suitable for areas away from SiO₂-containing dust, such as the upper structure of the working pool, breast walls near the burner ports, small furnace openings, and hanging walls.
