Temperature dependence of effective thermal conductivity and effective thermal diffusivity of Se90In10 bulk chalcogenide glass
چکیده انگلیسی

Measurement of effective thermal conductivity (λe) and effective thermal diffusivity (χe) of twin pellets of Se90In10 bulk chalcogenide glass has been carried out in the temperature range from 303 to 323 K and cooling from 323 to 303 K using transient plane source (TPS) technique. In the heating process variation of effective thermal conductivity (λe) and effective thermal diffusivity (χe) is observed. Both quantities are found to be maximum at 313 K, which lies in the vicinity of glass transition temperature (Tg). During the cooling process λe and χe remain same at all temperatures. Such type of behavior shows thermal hysteresis in this sample, which can be explained on the basis of structural change of the Se90In10 bulk chalcogenide glass.
