外文摘要：To provide a material with excellent comprehensive properties for the glass kiln melting pools,zirconia powder and alumina powder were fully mixed according to the ratio of m(ZrO2)∶m(Al2O3)=4∶1 and fused in an arc furnace.The obtained fused zirconia-corundum eutectic material was processed into different particle sizes,batched according to a certain particle size distribution and mixed evenly.After pressure molding and firing at 1 750 ℃,new zirconia-based composites were prepared.The phase composition and microstructure of the composites were analyzed.The molten glass corrosion resistance of the composites was compared with that of zirconia corundum bricks 33# and 41#.The results show that the new zirconia-based composites have a dense structure,high chemical purity without low melting point components,and good thermal shock resistance.Compared with zirconia corundum bricks 33# and 41#,after being corroded by high temperature molten glass,the new composites have no corrosion cavities,needle-like pores,defects or liquid phase infiltration,and no reaction with molten glass,showing good corrosion resistance to molten glass.
