Title

Preparation and Properties of Oxynitride Glasses Made from Potassium Metaphosphate

Abstract

Potassium phosphate oxynitride (KPON) glasses were made by heating crystalline KPO3 at 702° to 775°C in dry ammonia. the softening temperature, thermal expansion coefficient, refractive index, and dissolution rate in water were measured as a function of nitrogen content and compared with the properties of oxynitride glasses made from LiPO3 and NaPO3.
