Abstract
An apparatus has been developed with which thermal conductivities can be measured in the temperature range from 40°C to 100°C with a probable error of ±0.003 cal sec−1 cm−1 deg−1 or ±3 percent, whichever is the larger. It requires only a small sample (0.1875×0.1875×1.75 inches), does not require the attaching of thermocouples to the sample, and permits introduction and removal of the sample by remote control, if this is necessary. The apparatus is therefore especially useful to measure the thermal conductivity of large single crystals and also to observe the effect upon thermal conductivity of heat treatment, irradiation, or any other treatment that will not deform the sample yet which cannot be carried out readily with thermocouples attached to the sample.Keywords
