Abstract: Measurements of effective thermal conductivity (λe) and effective thermal diffusivity (χe) of twin pellets of Se80Te20-xInx (x= 2, 4, 6 and 10) chalcogenide glasses, prepared under pressure (load) of 5, 7 and 9 tons, have been made at room temperature, using transient plane source (TPS) technique. The results indicate that, both the values of λe and χe, increase with the increase of In concentration. Besides, λe and χe, also depend upon the load at which the pellets have been formed. The composition and pressure (load) dependent behaviour of λe and χe, is explained in terms of the ion-covalent type of bond which In makes with Se as it is incorporated in the Se-Te glasses.
