摘　　要：通过固相反应法在不同的烧结温度制备了一类新型的YSZ-Zr2WP2O12复合电解质材料,并通过XRD、Raman和SEM分析了烧结温度对复合材料的相成分和微观结构的影响. XRD和Raman谱的分析表明,在1400℃以上烧结得到的材料为YSZ-Zr2WP2O12复合电解质,没有其他杂质峰的存在;SEM分析表明,1500~1600℃烧结得到的复合材料晶粒尺寸较大,结构比较致密,有望得到较好的电学性能.因此,YSZ-Zr2WP2O12复合电解质的最佳烧结温度是1500~1600℃,该复合电解质材料的研究有望为解决电解质与电极之间热膨胀系数失配问题提供指导.A new kind of composite electrolyte materials YSZ-Zr2WP2O12 were prepared by solid state reaction at different sintering temperature. The effects of sintering temperature on the phase composition and microstructure of the composites were analyzed by XRD,Raman and SEM. The XRD and Raman spectra showed that the composites sintered at 1400 ℃ and above were YSZ-Zr2WP2O12 composite electrolytes,and there were no other impurity peaks.SEM analysis showed that the composites obtained by sintering at 1500-1600 ℃ had larger grain size and denser structure,and the better electrical properties would be expected to obtain. Therefore,the optimal sintering temperature of YSZ-Zr2WP2O12 composite electrolyte is 1500-1600 ℃. The research of this composite electrolyte material is expected to provide guidance for solving the problem of thermal expansion coefficient mismatch between electrolyte and electrode.
