Title

Nitrogen Dissolution in Alkali-barium-metaphosphate Melts

Abstract

Phosphorus oxynitride glasses were prepared by remelting 30R2O-20BaO-50P2O5, (R=Li, Na or K) glasses in anhydrous ammonia. The nitrogen content of these metaphosphate melts decreased with increasing size of the alkali ion. The dissolution rate in water and thermal expansion coefficient of the base glasses increased with increasing alkali ion size. The dissolution rate of the oxynitride glasses was lower than that of the base glasses but was essentially independent of the alkali ion. The thermal expansion coefficient of the oxynitride glasses increased with increasing alkali size as observed in other glasses.
