Thermal properties of neutron irradiated Se80Te10In10 glass

The thermal transport properties of Se80Te10In10 chalcogenide glass irradiated by slow neutrons for different time exposures were studied using the transient plane source method. The effective thermal conductivity (λ) and effective thermal diffusivity (χ) increase with exposure time of the material and reaches to a saturation value. Constant values of effective thermal conductivity and effective thermal diffusivity beyond a certain time exposure could be explained on the basis of decrease of concentration of Se–Te polymeric chains and Se–Te rings.
