Heat transfer in crystalline clathrate hydrates at low temperatures
The experimental results on the thermal conductivity k(T) of crystalline Xe, CH₄, and THF clathrate hydrates
 have been analyzed. In a wide region of temperatures above 2 K, k(T) exhibits a behavior typical of
 disordered solids, which depends weakly on their chemical composition, cr...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The experimental results on the thermal conductivity k(T) of crystalline Xe, CH₄, and THF clathrate hydrates
have been analyzed. In a wide region of temperatures above 2 K, k(T) exhibits a behavior typical of
disordered solids, which depends weakly on their chemical composition, crystalline structure and microstructure.
The results are discussed in the context of phenomenological models of phonon scattering by local
modes. It has been found that the Xe clathrate has a feature unusual for glasses, namely, k(T) decreases almost
two-fold as the temperature increases from 50–100 K. The behavior of k(T) is presumably determined
mainly by the strong phonon scattering on water molecules.
