Fused alumina brick is also known as Fused corundum brick, and fusedα-β block which is mainly composed of alumina, with a content of more than 94%. It is produced by melting high-purity alumina in an electric furnace at 2000℃ and then casting. α-β fused corundum brick is formed when α alumina and β alumina are combined in its crystallization stage. This process directly leads to the formation of a dense structure, so this block has good resistance to strong alkalinity.

At 1350℃, it has strong corrosion resistance and hardly contaminates the molten glass. Because it does not contain impurities such as Fe2O3 and titanium dioxide, when it comes into contact with the molten glass, bubbles are rarely generated.

Therefore, this product has the characteristics of reducing pollution to the molten glass. With excellent performance, fused cast alumina blocks (α-β blocks) are mainly used as ideal refractory supply channels, lip bricks and working ends of glass melting furnaces.
