Thermal Behavior of Novel (GeS2)1-X(AgI)X Glasses

Conference paper
Part of the NATO Science for Peace and Security Series B: Physics and Biophysics book series (NAPSB)

Novel chalcohalide glasses have been developed. The amorphous nature of the synthesized Ge—S—AgI materials has been proven by means of X-ray diffraction. Differential scanning calorimetry has been used to investigate the thermal characteristics of the materials to derive information about the glassy structure. The glass transition (Tg), the onset of crystallization (Ton), and the peak crystallization (Tcr) and melting (Tm) temperatures have been determined in the temperature range of 293—750 K. The criteria for thermal stability (ΔT) and the glass-forming ability (Hgl and S) have been calculated.
