Fused cast beta alumina blocks is produced by melting and casting high

purity alumina in electric furnace at 2000C. Beta corundum is made of 100%

beta alumina, has strong spalling resistance, especially to strong alkaline

stream resistance. This product does not contain impurities that may

contaminate melting glass. Best be used on the top of the structure where

less scattered glass material.

Typical chemical composition:

AL2O3 no less than 93%

SiO2 no more than 0.5%

Na2O 5.5-6.5%

Fe2O3 trace

TiO2 trace
