Using the laser flash method the thermal conductivity of the Rb-Bi liquid alloy with a bismuth content of 27 at. % was measured in the temperature range from the liquidus point to 1173 K. Approximation equations for thermal conductivity and thermal diffusivity have been obtained, and a table of reference data has been developed. An analysis of the measurement results confirms the existing assumption of the presence of intermetallic complexes with a partially ionic nature of the interatomic interaction in Rb-Bi melts.

液态Rb 73 Bi 27合金的导热系数

使用激光闪光法，铋含量为27 at。2的Rb-Bi液态合金的热导率。在从液相线点到1173 K的温度范围内测量％。获得了热导率和热扩散率的近似方程，并且已经开发了参考数据表。对测量结果的分析证实了Rb-Bi熔体中存在金属间配合物的现有假设，该金属间配合物具有部分离子性质的原子间相互作用。
