Twenty-three glasses in the soda-alumina-zirconia-silica system were prepared and characterized in terms of resistivity, activation energy for conduction, and glass transition temperature. In the high-soda region of the system, 40 to 42 mol % soda, the glasses were found to possess resistivities in the range of 130 to 160 ohm-cm at 300/sup 0/C. The additives, Al/sub 2/O/sub 3/ and ZrO/sub 2/, were found to improve the conductivity of the glasses as well as their chemical stability toward Na, Na/sub 2/S/sub 4/, S, and Na/sub 2/S/sub 3/ (400/sup 0/C for 1000 h). The high-soda quaternary glasses were found to have chemical stabilities comparable to those of the Dow borate glass and Ceramatec ..beta..''-alumina. Thermal expansion coefficients of selected high-soda glasses are in the range of 16 to 19 x 10/sup -6///sup 0/C. Based on these results, the following glass composition has been selected for further testing (in mol %): 42 Na/sub 2/O, 8 Al/sub 2/O/sub 3/, 5 Zr O/sub 2/, and 45 SiO/sub 2/. Using this glass, preliminary cell performance calculations indicate the potential for very high specific power and specific energy.
