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

다국어 초록 (Multilingual Abstract)

Measurement of eective thermal conductivity (ke) and eective thermal diusivity (ve) of twin pellets of Se90In10 bulk chalcogenideglass 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 eective thermal conductivity (ke) and eective thermal diusivity (ve) is observed. Bothquantities are found to be maximum at 313 K, which lies in the vicinity of glass transition temperature (Tg). During the cooling processkeand ve remain same at all temperatures. Such type of behavior shows thermal hysteresis in this sample, which can be explained on thebasis of structural change of the Se90In10 bulk chalcogenide glass.
