Products Description

Fused Casting Zirconia Electrocast S3 ER1681 Refractory Blocks AZS Block Zircon Corundum Brick

Fused Casting Zirconia Electrocast S3 ER1681 Refractory Blocks AZS Block Zircon Corundum Brickwith 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, High Erosion Resistance Fused AZS Refractory Blocks 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, High Erosion Resistance Fused AZS Refractory Blocks is the eutectoid of corundum phase and baddeleyite phase, and vitreous phase is filled among their crystals.
