Exploring Azs Fused-Cast Refractories

Alumina-zirconia-silica (AZS) fused cast refractories began to increase in popularity in glass furnace applications for the glass contact and superstructure market in the middle of the last century. AZS fused-cast refractories were intrinsically superior to the previously utilised silico-alumina sinter materials, and they enabled a significant evolution in furnace design while allowing for the extensions of furnace campaign life. AZS fused-cast refractories have evolved from a speciality product to a commodity, but is their future viability in question?
