采用电磁悬浮法测量了M-Si（M=Fe，Ni，Ge）二元合金在液态下的密度，并结合静磁场测量了它们的摩尔体积。我们系统地分析了摩尔体积与组成的关系。虽然液态Ge-Si合金的摩尔体积的浓度依赖性服从指示理想混合物的线性规律，但是相比之下，Ni-Si合金的摩尔体积的浓度依赖性与Fe-Si系统的摩尔体积的线性规律显示出很大的差异。为了分析偏摩尔体积，讨论了组成原子之间的相互作用。
The molar volumes of binary M–Si (M=Fe, Ni, and Ge) alloys in a liquid state were obtained from their densities measured using electromagnetic levitation coupled with a static magnetic field. We have systematically analyzed the molar volume as a function of composition. Although the concentration dependence of the molar volume of the liquid Ge–Si alloys obeys a linear law which is indicative of an ideal mixture, in comparison, that of the Ni–Si alloys shows a large discrepancy from the linear law as well as the Fe–Si system. The interaction between the constituent atoms was discussed with a view to analyzing the partial molar volume.
