Investigation of thermal conductivity and thermal diffusivity of liquid bismuth within the temperature range of $545$–$970$ K

Thermal conductivity and thermal diffusivity of liquid bismuth within the temperature range from $545$ K up to $970$ K are investigated by the laser flash method. The measurement errors are equal to $(3.5$–$4.5)\%$. Approximating equations are obtained, and the reference tables are presented for the temperature dependencies of the properties. The measurement results are compared to the published data available. The temperature dependence of the Lorentz number is calculated up to $970$ K.
