Sulfide glasses capable of conducting alkali metal ions are prepared from a nonmetal glass former such as GeS[sub 2], B[sub 2]S[sub 3] and SiS[sub 2] in mixture with a glass modifier such as Na[sub 2]S or another alkali metal sulfide. A molten mixture of the constituents is rapidly quenched to below the glass transition temperature by contact with a metal mold. The rapid quench is sufficient to prevent crystallization and permit solidification as an amorphous solid mixture. An oxygen-free atmosphere is maintained over the mixture to prevent oxidation. A new glass system of (1-X) Na[sub 2]O:XB[sub 2]S[sub 3] is disclosed. 4 figs.
