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.
