Sodium ion conducting sodium borophosphate glass

摘要

Certain sodium borophosphate glasses containing 0 to 11 mole percent of one or more oxides selected from the group consisting of ZrO2, MgO and Al2O3 are good ionic conductors and are resistant to molten sodium at about 300 DEG C. Exemplary is a glass consisting of 55 mole percent of Na2O, 25 mole percent of B2O3, 20 mole percent of P2O5 and 5 mole percent of ZrO2.
