Abstract :Differential scanning calorimetric (DSC) studies have been carried out for Ge-Sb-S and Ge-Sb-Se ternary glasses. The glass transition temperatures,crystallization temperatures and melting temperatures for these ternary glasses were determined from DSC curves. The glass forming ability and the activation energy for crystallization were obtained for GeSb_4S_7, Ge_2Sb_2S_5, GeSb_2Se_5 and GeSb_4Se_8 glasses. The values of the glass forming ability for these ternary glasses are over 0.4, which indicates that these glasses are good glass formers. The activation energies for the crystallization are about 50 kcal/mol for GeSb_2Se_5 and GeSb_4Se_8 glasses and show less composition dependence. On the other hand, the activation energies for Ge-Sb-S glasses indicate the tendency of decrease with increasing the composition of Sb_2S_3.
