| Abstract: | Our earlier experimental data on the thermal conductivity of porous glass and of the porous glass + NaCl composite in the temperature interval 25–300 K are analyzed from a different standpoint. It is shown that the thermal conductivity of sodium chloride filling randomly arranged nanochannels in porous glass behaves exactly like that of a strongly disordered crystalline system and can be described in terms of Einstein’s model of the thermal conductivity of solids. |
