Abstract:The glass-forming ability is studied in the NaF–ZnSO4 system. It is revealed that, when melts are cooled at a rate of 103 K/s, the glass formation is observed in the concentration range 35–70 mol % ZnSO4. The characteristic temperatures are determined by differential thermal analysis. According to these temperatures, fluorosulfate glasses can be assigned to low-melting glasses. The density of glasses is measured by hydrostatic weighing. The experimental data obtained are used to calculate the molar volume and the thermal stability parameters of fluorosulfate glasses.
