摘　　要：研究了不同氧化锆、碳含量以及添加剂对Ａｌ＿２Ｏ＿３－ＺｒＯ＿２－Ｃ试样的强度、抗热震性、抗氧化性及抗侵蚀性的影响。认为随ＺｒＯ＿２或碳含量的增加，试样的强度有所下降，抗热震性和抗侵蚀性显著改善。添加少量Ｓｉ粉能显著提高试样的常温强度、抗氧化性能及抗侵蚀性．ＳｉＣ粉对试样性能的改善作用不大。The strength,the thermal shock resistance and oxdation resistance as well as the corro-sion resistance of Al2O3-ZrO2-C blocks with various contents of ZrO2,carbon and additions are investigated.It is shown that with an increase of the content of C or ZrO2,the strength is decreased but the thermal shock resistance and corrosion resistance are improved.The addi-tion of Si powder can greatly improve the strength at room temperature,the oxidation resist-ance and corrosion resistance. However,the addition of SiC powder contributed little to the improvement of the sample performance.
