The temperature dependence of the thermal conductivity is shown in Figure . The thermal conductivity decreases approximately monotonically with temperature yielding values of 4 × l0 -3 W/cm K at 300 K to 6 × l0 -4 W/cm K at 4.2 K. Ashworth and Rechowicz 2 found 2.1 × l0 -3 W/cm K near 300 K for a th
Abrupt increases in the thermal conductances of Apiezon N and T grease have been observed, and it is surmised that these discontuities, as well as published anomalies in the specific heat, are related to glass transition temperatures (Tg (N) = 273 K and Tg (7") = 210 K)of the greases.
The specific heat of 304 stainless steel has been measured in the temperature range 70-600 mK. A Schottky anomaly has been found and the data can be represented by C(T) = (465T+0.56F2) PJ g-l K-l. This large specific heat can lead to long thermal relaxation times in low temperature apparatus, especi
