Abstract

　We have used X-ray absorption technique combined with a large-volume press to determine the density of the Fe-Ni-S liquid alloys at 3 GPa. The measured densities are consistent with the adiabatic compression curve of F-S liquids determined from sound velocity measurements. The molar volume of the FeS-NiS binary liquids shows a negative deviation from the ideal solution.
