采用溶胶-凝胶法制备了具有NASICON型结构的新型三价阳离子导体R1/3 Zr 2（PO 4）3（R：稀土），并对其三价离子导电性能进行了研究。随着R3+半径的增大，晶格膨胀，电导率降低。在R1/3 Zr 2（PO 4）3中，Sc 1/3 Zr 2（PO 4）3的电导率最高，其中Sc 3+的含量最小。通过直流电解直接证明了Sc 1/3 Zr 2（PO 4）3固体电解质中Sc 3+离子的导电性。
New trivalent cationic conductors with NASICON-type structure, R1/3Zr2(PO4)3(R: rare earths), were prepared by a sol–gel method and the trivalent ionic conducting properties were investigated. As increasing the R3+radius, the lattice expanded and the conductivity decreased. The Sc1/3Zr2(PO4)3which contained the smallest trivalent cation in the rare earth series, Sc3+, showed the highest conductivity among the R1/3Zr2(PO4)3as expected from relationship between the migrating cation size and the lattice volume. The trivalent Sc3+ion conduction in the Sc1/3Zr2(PO4)3solid electrolyte was directly demonstrated by a dc electrolysis.
