| Summary |
"The purpose of this research is to investigate possible methods of determining the thermal conductivity of small poorly conducting samples at elevated temperatures, and, further, to assemble a suitable apparatus, followed by measurement of thermal conductivity of one or more cubic lattice samples. Basic requirements of the apparatus are few. It is first required that the measurement of thermal conductivity be made over a considerable range temperature. It is also preferred that the basic apparatus be placed in a vacuum where undesirable heat flow by convection is eliminated and air corrodible samples are preserved. The apparatus must use only the smallest samples from which accurate results may be obtained. The thermal conductivity temperature relation is not linear, so only small temperature intervals may be used"--Introduction, leaf 2. |
