Abstract
A comparative investigation is made of the heat conduction of ruby, quartz, and lithium niobate by direct measurement and by a calculation using the Debye formula on the basis of phonon interaction data from measurements of the absorption of hypersound. Methods are described and results of measurements of the heat conductivity, ultrasound velocity, and hypersound absorption coefficients are obtained in a broad temperature range.
