摘　　要：介绍了纳米技术在氧离子导体和氟离子导体的制备及导电性能研究方面的应用。纳米尺度的氧化物在烧结过程中致密化温度可降低50～200℃,最终产物的晶粒尺寸可小于1μm,离子电导率较高,可达到10–1S·cm–1量级。纳米氟离子导体与传统粗晶氟离子导体相比,具有明显的纳米尺寸效应,导电激活能可降低30%,离子电导率可提高1～2个数量级。Introduced were the applications of nano-technology in the fabrication and conductive property research of oxide （oxygen） ionic conductors and fluoride （fluorine） ionic conductors. The densification temperature of nanosize oxide in sintering process is decreased by 50-200℃. The ionic conductivity of the final product can be as high as 10^-1 S·cm^-1 and the grain size can be smaller than 1 μm. Nanosize fluoride ionic conductors exhibit obvious nanosize effects, The activation energy for ionic conductivity of nanosize fluoride ionic conductors can be 30% lower than that of the traditional coarse crystalline fluoride, and the ionic conductivity is increased by 1 -2 orders of magnitude.
