Abstract: The magnesia ceramic specimens were prepared by high purity magnesia powder and nano-monoclinic zirconia powder as raw material. The specimens were sintered at 1 350 ℃, 1 450 ℃ and 1 550 ℃ for holding 2 hours, respectively. The effects of adding quantity of nano-monoclinic zirconia and sintering temperature on the sintering property and thermal shock resistance of magnesia ceramic were investigated. The results show that the densification and the microstructure homogeneity are improved, sintering temperature is decreased by adding monoclinic zirconia into magnesia ceramic. The thermal shock resistance of specimens with nano-monoclinic zirconia is improved due to mechanisms of microcrack toughening, phase transformation toughening and crack deflection toughening. The optimal scheme to improve thermal shock resistance of magnesia ceramic is adding 12wt% monoclinic zirconia and sintering at 1 450 ℃.
