Description
| - The crystal growth kinetics of antimony sulphide in (GeS2)0.3(Sb2S3)0.7 glass has been studied by DSC and microscopy. The linear crystal growth kinetics has been observed in the temperature range 271 T 310 °C (EG=288 7 kJ?mol-1). In fact the crystal growth takes place in the volume of highly viscous (4?107 3?104 Pa?s), supercooled melt. The applicability of standard growth models has been assessed. From the reduce growth rate plot (i.e., growth rate corrected for viscosity) as a function of supercooling we find that the most probable mechanism is the interface controlled 2D nucleated growth. The non-isothermal DSC data, corresponding to the bulk sample, can be described by the Johnson-Mehl-Avrami equation that provides a reasonable description of crystallization behavior also for partially crystallized samples. However, further analysis of DSC data reveals that this equation cannot be applied for the powder sample even in isothermal conditions.

- Kinetika růstu krystalů sulfidu antimonitého ve skle (GeS2)0.3(Sb2S3)0.7 byla studována pomocí DSC a mikroskopie. V teplotním rozsahu 271 T 310 °C (EG=288 7 kJ?mol-1) byl pozorován lineární růst krystalů. Sledovaný růst krystalů probíhal u vzorků ve stavu podchlazené taveniny (vysoká viskozita 4?107 3?104 Pa?s). Byly testovány standardní modely růstu. Ze závislosti redukované rychlosti růstu (tj. rychlost růstu s korekcí na viskozitu) na podchlazení bylo zjištěno, že nejpravděpodobnější mechanismus je 2D nukleační růst. Neizotermní DSC data pro objemový vzorek mohou být popsána Johnson-Mehl-Avrami rovnicí, která také dostatečně popisuje krystalizaci částečně zakrystalovaných vzorků. Nicméně další analýza DSC dat ukazuje, že tato rovnice nemůže být použita pro popis krystalizace práškových vzorků. (cs)
