Critical analysis of the different glass stability criteria in chalcogenide glasses

Abstract In this endeavor, various glass stability criteria have been discussed by using two ternary alloys of SeTePb glassy system. These criteria can be obtained based on the interrelationship between the characteristic temperatures. Differential Thermal Analysis measurements under the non-isothermal conditions can be used for this purpose. Two groups of these criteria according to the onset and peak crystallization temperatures have been studied as a function of composition. The heating rate and composition dependences of all criteria concluded that the CZW and CLX criteria are not suitable to discuss the glass stability (GS) for the studied compositions. The extracted data from various GS criteria and their relative change parameters reveal that the criterion CYL of Yuan et al is best and it exhibits the best ability for apprising the GS.
