The multi-component quaternary materials of the Se78-xTe20Sn2Bix (x = 0, 2, 4, 6) chalcogenide glasses system were synthesized with varying bismuth (Bi) composition by using a melt quenching technique. The thermal transport properties (effective thermal conductivity, diffusivity, and specific heat per unit volume) of the glasses were determined using the transient plane source (TPS) technique at room temperature. The TPS measurements found ...
The Transient Plane Source (TPS) technique was used to evaluate the thermal transport characteristics (such as thermal conductivity, thermal diffusivity, specific heat per unit volume) in multi-component Se78-xTe20Sn2Pbx glasses at room temperature. From the experimental results, it was noted that thermal conductivity decreased with lead (Pb) content in the ternary Se78Te20Sn<...
Selenium (Se) and tellurium (Te) based glasses have unique physical and chemical characteristics that can be manipulated with by the addition of metal alloys. In this study, the thermophysical properties of Se80Te20 and Se80Te10M10 (where M = cadmium (Cd), indium (In), and antimony (Sb)) chalcogenide (containing one or more S, Se, or Te) glasses are investigated to test their use in industrial applications. The transient plane source (TPS) ...
The influence of In content in the Se98-xAg2Inx (x = 0, 2, 4, 6) system of chalcogenide glasses on the physical properties of the glasses were investigated by the authors. The maximum thermal conductivity and thermal diffusivity value was observed for the sample containing 2 at. % In. The microhardness was found to initially decrease upon doping of In for Se; however, it began to slowly increase after a certain In content had been attained. ...
A chalcogenide glass was prepared and doped with carbon nanotubes (CNTs) in an effort to increase the electrical and thermal conductivity of the glass. The glass that was used in this study was Se85Te10Ag5 which was prepared by melt-quenched method. CNTs were added to the glass at 3 and 5 wt. % and the properties of the composite glasses were compared with those of the pure chalcogenide glass. It was found ...
