Mechanical Properties and Crystallization Behavior of GeS2–Sb2S3–In2S3
glass‐ceramics were prepared by heat‐treating the base glass above Tg for different durations. The results of Raman spectra and XRD patterns show that the first precipitated crystals during the heat treatment
are In2S3 and the crystallization of the Sb2S3 and GeS2
subsequently occurs. Bulk samples heat‐treated at 295°C for different heating rates and durations are used to study the crystallization mechanism and evolution of the three crystallization peaks (CPs). It is found that three CPs partly overlap with each other and then separate with
increasing heat‐treating durations.
