Thermal conductivity of argon–SiO₂ cryocrystal nanocomposite

The effective thermal conductivity of samples of cryocrystal nanocomposite obtained from argon and SiO2
 nanopowder was determined in the temperature interval 2–35 K using the steady-state method. The thermal conductivity
 of crystalline argon with nanoparticles of amorphous silica o...

description The effective thermal conductivity of samples of cryocrystal nanocomposite obtained from argon and SiO2
 nanopowder was determined in the temperature interval 2–35 K using the steady-state method. The thermal conductivity
 of crystalline argon with nanoparticles of amorphous silica oxide embedded in its structure shows a weak dependence
 on particle linear dimension in the interval 5–42 nm. The temperature dependence of the thermal conductivity
 of the nanocomposites can be well approximated by taking into account only the two mechanisms of heat
 carrier scattering: phonon-phonon interaction in U-processes and scattering of phonons by dislocations.
