Crystallization behavior of (GeS2)0.1(Sb2S3)0.9 glass

Abstract: The crystal growth kinetics of antimony trisulfide in (GeS2)0.1(Sb2S3)0.9 glass has been studied by microscopy and DSC. The linear crystal growth kinetics has been confirmed in the temperature range 492⩽ T ⩽515K (E G =405±7kJmol−1). The applicability of standard growth models has been assessed. From the crystal growth rate corrected for viscosity plotted as a function of undercooling it has been found that the most probable mechanism is interface controlled 2D nucleated growth. The non-isothermal DSC data, corresponding to the bulk sample, can be described by the Johnson–Mehl–Avrami equation. [Copyright &y& Elsevier]
