Fused Cast AZS Refractory Brick Series for Internal Structure of
Opal GlassFused Cast AZS Refractory Brick Series for Internal Structure of
Opal Glass with 33% of ZrO2 are produced by batching well-chosen zircon sand
and industrial alumina powder with a certain ratio, adding with a
small amount of sodium carbonate as Na2O source and boric acid or
borax as B2O flux source, mixing well,melting and casting under
1800ºC~1900ºC. Based on above process, Fused Cast AZS Refractory Brick Series for Internal Structure of
Opal Glass with 36%~41% of ZrO2 are supposed to be produced by adjusting
formula and adding some desilication zirconia as raw material.
Their petrographic structure is composed of eutectoid and glass
phase of corundum and baddeleyite. From the perspective of phase, Fused Cast AZS Refractory Brick Series for Internal Structure of
Opal Glass is the eutectoid of corundum phase and baddeleyite phase, and
vitreous phase is filled among their crystals.
