This study focused on the effect of Zr-inclusion on Na+ conduction properties of the newly developed glass–ceramic solid solutions of Na5FeSi4O 1 2 and Na4ZrSi4O 1 2 . We experimentally confirmed formation of an all proportional solid solution in the range of x = 0 and 1.0 with the composition Na5 − x Fe1 − x Zr x Si4O 1 2 . Glass–ceramic with a fast Na+ -conducting Na5YSi4O 1 2 -type single phase was obtained in all the solid solutions. The conduction properties of the glass–ceramics were improved with increasing content of Zr, and Na4ZrSi4O 1 2 was the most conductive glass–ceramic. The ionic conductivities were as high as 1.9 × 10− 5 S cm− 1 and 9.3 × 10− 3 S cm− 1 at temperatures of 25∘C and 300 ∘C, respectively. The improved conductivity was attributed to the expansion of the conduction path by larger Zr ions replacing FeO6 octahedra.
