Thermal Diffusivity Measurement of Cerium in the Temperature Range of 300-1800 K

The thermal conductivity of cerium in the solid and liquid states, including the phase transition, in the temperature range of 293–1800 K was measured for the first time by the laser-pulse method with an accuracy of 2–5%. Comparison of the results with the available literature data was made. Data for the 293–400 K temperature range were obtained for the first time. Reference tables on the thermal conductivity and thermal diffusivity of cerium were developed for scientific and practical use.
