Title

Cation Effects in NaPO3 Glasses Doped with Metal Nitrides and Oxides

Abstract

Oxynitride glasses were prepared by doping a NaPO3 melt with either AIN, Mg3N2, or Ca3N2 NaPO3 glasses doped with AI2O3, MgO, or CaO, so as to contain the same weight percent of each cation as in the oxynitride glasses were also prepared. The dissolution rate in water and the thermal expansion coefficient both decreased while the dilatometric softening point, glass transition temperature, and refractive index increased with increasing nitride or oxide dopant concentration. The properties of the corresponding oxide- or nitride-doped glasses were essentially equal, which indicated that the cation was primarily responsible for the change in each property.
