    Crystal growth kinetics in (GeS2)0.2(Sb2S3)0.8 glass

  • Original language description

    The crystal growth kinetics of Sb2S3 in the (GeS2)0.2(Sb2S3)0.8 glass has been studied by DSC and optical microscopy. The linear growth kinetics of Sb2S3 has been observed in the temperature range 525 K &#61603; T &#61619; 556 K (EG=295 &#61617; 3 kJ*mol-1). From the reduce growth rate plot (i.e., growth rate corrected for viscosity) as a function of supercooling it has been found that the most probable mechanism is interface controlled 2D nucleated growth. The DSC data, corresponding to the bulk sampleunder isothermal and non-isothermal conditions, can be described by the Johnson-Mehl-Avrami equation for the kinetic exponent m&#61504;2

    Kinetika růstu krystalů ve skle (GeS2)0.2(Sb2S3)0.8

  • Czech description

    Kinetika růstu krystalů Sb2S3 ve skle (GeS2)0.2(Sb2S3)0.8 byla studována pomocí DSC a optické mikroskopie. Lineární růst krystalů Sb2S3 byl sledován v oblasti teplot 525 K &#61603; T &#61619; 556 K (EG=295 &#61617; 3 kJ*mol-1). Ze závislosti redukované rychlosti růstu (tj. rychlost růstu s korekcí na viskozitu) na podchlazení bylo zjištěno, že nejpravděpodobnější mechanismus je 2D nukleační růst. DSC data pro objemový vzorek za izotermních i neizotermních podmínek mohou být popsána pomocí Johnson-Mehl-Avrami rovnice s parametrem m&#61504;2.
