Product Description
FUSED CAST BRICK alpha-beta Al2O3
Fused cast AZS (alumina, zirconia and silica) firebricks are mainly categorized into 33#, 36# and 41# according to different zirconia's contents from 33% to 41%.
Fused cast alumina (alpha-beta; Al2O3 and β Al2O3) firebricks are composed of alpha alumina, beta alumina and small amount of glass phase.
Both AZS and alumina firebricks have shown excellent performance in glass furnace construction.
