內容簡介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(Zr O2) : 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 °C, 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.
