摘　　要：介绍了Cr2O3-Al2O3-ZrO2制品的组成及各组成的作用、烧成气氛、制品的显微结构特征和性能指标。着重论述了影响制品性能的烧成工艺和以电熔、烧结两种Cr2O3颗粒生产的Cr2O3-Al2O3-ZrO2制品的显微结构差异,表明在还原气氛下烧成的Cr2O3-Al2O3-ZrO2制品性能优良,而采用电熔Cr2O3料生产的Cr2O3-Al2O3-ZrO2制品性能优于使用烧结Cr2O3料生产的。Components and their functions,firing atmosphere,microstructure and properties of Cr2O3-Al2O3-ZrO2 refractories were introduced.Effect of sintering process on properties of Cr2O3-Al2O3-ZrO2 refractories was researched,and microstructures of two Cr2O3-Al2O3-ZrO2 products produced with fused Cr2O3 grains and sintered Cr2O3 grains,respectively,were compared.The results show that the Cr2O3-Al2O3-ZrO2 refractories fired in reduction atmosphere has good performance,and the properties of the Cr2O3-Al2O3-ZrO2 refractories using fused Cr2O3 grains are better than those of the refractories using sintered Cr2O3 grains.
