摘要
The kinetics of crystallization in 70GeS2-20Sb2S3-10CsCl chalcogenide glass was studied using differential scanning calorimetry （DSC） at different heating rate. The values of glass transition and crystallization temperatures were found to be heating rate dependent. Using Matusita method, the crystallization activation energies E and crystallization parameter （n） calculated are 348.08±0.99 kJ/mol and 1.78. It suggests that there are two mechanisms： a surface and one-dimensional crystallization processes.
