Rapid synthesis of chalcogenide glasses of Se–Te–Sb system by microwave irradiation

Abstract

In this paper we report the rapid synthesis of Se–Te based chalcogenide glasses through microwave irradiation without the help of metal powders. Mixtures of chalcogens can be made to couple to microwaves when at least one constituent of the mixture has a relatively higher electrical conductivity. Also, this constituent has to be in powder form. The glasses thus prepared have been characterized by thermal analysis and x-ray analysis, and it has been confirmed that the Tg values of our samples are comparable to the already reported Tg values for samples prepared by conventional methods. Thus, this type of rapid synthesis may replace the prolonged conventional procedures for synthesis of these glasses.
