ABSTRACT:
Certain sodium aluminum phosphate glasses containing up to 11 mole percent of ZrO.sub.2, MgO or SiO.sub.2 are good ionic conductors and are resistant to corrosion by molten sodium at about 300.degree. C. Exemplary is a glass consisting of 50 mole percent Na.sub.2 O, 38 mole percent P.sub.2 O.sub.5, 12 mole percent Al.sub.2 O.sub.3 2 mole percent MgO and 4 mole percent SiO.sub.2.
