Study of thermal conductivity close to the melting point
Vladimir Golyshev, Michael Gonik, Vladimir Tsvetovsky
Methods of measuring the thermal conductivity of materials in solid and liquid state at high temperatures are reviewed. Factors influencing the accuracy of the obtained results are examined. Special attention is paid to the role of contact resistance. Results for the thermal conductivity of sodium chloride, bismuth germanate, and germanium over a wide temperature range are presented. The behaviour of thermal conductivity during melting of these materials is analysed.
