The concentration dependences of molar volume, thermal expansion coefficient, and interdiffusion coefficient for liquid lead–magnesium system

The coefficients of binary diffusion for liquid lead–magnesium alloys (19.11, 33.45, 52.46, and 83.06 at.% Pb) have been measured at 950 K by a γ-ray attenuation technique. Literature data on the thermal properties of Mg–Pb melts have been summarized. The composition dependences of molar volume, volumetric thermal expansion coefficient, and interdiffusion coefficient in the liquid state have been constructed and discussed.
