Abstract: Differential Thermal Analysis ((DTA) has been used to determine the characterstic temperatures of glass transition, crystallization and melting temperatures in amorphous Se-Te-Sn alloys. The effect of Sn on the binary SeTe system is discussed. The correlation between the glass transition temperature and coordination number of Sn atoms in multicomponent chalcogenide glasses is verified. The difference in crystallization and glass transition temperature is used to define the stability and glass forming ability in the alloys. S parameter is defined using the difference to assign stability in a quantitative way. It is found that composition containing Sn 6 at% is most stable in the present system.
