Glass forming ability and thermal stability parameters of Se85Te15-x Sbx chalcogenide glasses

Abstract

Various glass stability criteria have been presented in this work using three ternary alloys of Se85Te15- xSbx (x = 2,4&6 at. %) glassy system. These criteria can be obtained by using the interrelationship ship between the typical temperatures. For this, differential scanning caliometry measurements in non-isothermal settings can be used. The KGL criterion was shown to be ineffective in discussing glass stability (GS) for the compositions studied due to its dependence on heating rate and composition. The data from various GS criteria and their relative change parameters suggest that Yuan et al.'s criterion KYL is the best and has the best ability to apprise the GS. By increasing Sb content, all criteria indicate that thermal stability improves.
