The effect of composition variations on thermal and crystallization properties of Sb–S–I glass system is investigated by differential thermal analysis (DTA) and X‐ray diffraction (XRD). In general, the glass transition temperature ( T g ) and the temperature corresponding to the maximum crystallization rate ( T p ) are found to decrease with increasing iodine concentration for a fixed Sb/S ratio. However, precipitation of SbSI phase is sensitive to the Sb/S ratio for a given iodine fraction. The optimal composition and its devitrification behavior for forming only the ferroelectric SbSI phase are established on the basis of DTA curves and XRD patterns.
