Abstract
The thermal conductivities of German silver, stainless steel and constantan have been determined between 2 and 90° K. and the electronic and lattice components of the conductivity have been calculated. The electronic conductivity is limited by scattering by “impurities”. The lattice conductivity is limited by scattering of the lattice waves by electrons at the lower temperatures and by “impurities” at higher temperatures. A table is given showing the heat flow along specimens of each alloy resulting from temperature differences eommonly met with in practice in low-temperature work.Keywords
