Description
High alumina fused cast products is produced by melting and casting high purity alumina
in electric furnace at 2000C. High alumina fused cast blocks is formed when alpha 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.
Chemical composition typical value:
AL2O3 more than 95%
SiO2 less than 0.5%
Fe2O3+TiO2+CaO less than 0.5%
Na2O remnant
