The particle size influence on crystallization kinetics of (GeS2)0.1(Sb2S3)0.9 glass

The dependence of crystallization process on the particle size was studied for the pseudobinary chalcogenide glass (GeS2)0.1(Sb2S3)0.9. Crystallization of Sb2S3 component was studied under isothermal and non-isothermal conditions using DSC. The strong dependence of crystallization process on the particle size was observed. With the increase of particle size the crystallization temperature range shifts to higher temperatures. This was observed for both isothermal and non-isothermal conditions. The activation energy of the process is for isothermal experiments higher than for non-isothermal experiments. The crystallization process was for all the samples described using autocatalytical model. Corresponding kinetic parameters are for crystallization under isothermal conditions lower than for non-isothermal crystallization.
