- Abstract
To provide a material with excellent comprehensive properties for the glass kiln melting pool, zir- conia 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 sintering 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 corroded by high temperature molten glass, the new composites have no corrosion cavities, no needle-like pores or defects or liquid phase infiltration and no reaction with molten glass, showing good corrosion resistance to molten glass.
