Viscosity And Surface Tension Of Oxynitride Glass Melts

The viscositites and surface tensions of three MgO-Al2O3-Y2O3-SiO2-based oxynitride glass melts were measured. Glass transition temperature, Littleton temperature and sink-in temperature were obtained, and by using the Vogel-Fulcher-Tammann equation the viscosities were calculated from Tg (820 to 940 deg C) to 1600 deg C.
