Fused cast alpha-beta alumina products is produced by melting and casting high purity alumina in electric
furnace at 2000C. alpha-beta cast alumina products is formed when alpha alumina and beta alumina
inter-combine during their crystallization stage. A very compact structure is then formed; it has excellent
endurance to strong alkali. Under 1350C, the corrosion resistance to glass melt is the same as AZS products.
Because it does not contain impurities such as Fe2O3 and TiO2, when comes into contact with liquefied glass,
air bubbles are rarely found. Therefore, this product has the special characteristic of minimizing contamination
to glass liquor. So it is very suitable for sidewalls, pond bottoms, fore-hearth feeders of slap-up glass kiln.
