Extraordinary temperature dependence of isochoric thermal conductivity of crystalline CO₂ doped with inert gases
The isochoric thermal conductivities of solid (CO₂)₀,₉₀₅Kr₀,₀₉₅ and (CO2)₁₋xXex(x = 0.052 and 0.097) solution of different densities was investigated in the temperature interval from 150 K to the onset of melting. An unusual effect of point defects on the thermal conductivity has been detected. I...

| description |
The isochoric thermal conductivities of solid (CO₂)₀,₉₀₅Kr₀,₀₉₅ and (CO2)₁₋xXex(x = 0.052 and
0.097) solution of different densities was investigated in the temperature interval from 150 K to
the onset of melting. An unusual effect of point defects on the thermal conductivity has been detected.
In pure CO₂ at T >150 K the isochoric thermal conductivity decreases smoothly with increasing
temperature. In contrast, the thermal conductivity of solid CO₂/Kr and CO₂/Xe solutions
first decreases passing through a minimum at 200–210 K and then starts to increase with
temperature up to the onset of melting. This behavior of the isochoric thermal conductivity is attributed
to the rotation of the CO₂ molecules which gains more freedom as the spherically symmetrical
inert gas atoms dissolve in CO₂. |
