Kucera, G H; Roche, M F

An ionically conductive glass is disclosed for use as electrolyte in a high temperature electrochemical cell, particularly a cell with sodium anode and sulfur cathode. The glass includes the constituents Na/sub 2/O, ZrO/sub 2/; Al/sub 2/O/sub 3/ and SiO/sub 2/ in selected proportions to be a single phase solid solution substantially free of crystalline regions and undissolved constituents. Other advantageous properties are on ionic conductivity in excess of 2 X 10/sup -3/ (ohm-cm)/sup -1/ at 300/sup 0/ C. and a glass transition temperature in excess of 500/sup 0/ C.
