Mechanochemical synthesis of fluoride-ion conducting glass and glass–ceramic in ZrF4–BaF2 binary system

Abstract

Abstract Fluoride glasses in the binary system ZrF4–BaF2 were prepared via mechanochemical treatment. The glass-forming region of the ZrF4–BaF2 system obtained using the mechanochemical method was wider than that obtained using the conventional melt-quenching method. The glass–ceramic 60ZrF4·40BaF2 (mol%) sample was obtained by heat treatment and shows a higher conductivity of 1.2 × 10–6 S cm−1 at 200 °C than the pristine glass. This study revealed that mechanochemical treatment was effective for the synthesis of fluoride glasses.
