Abstract

We report a method of measuring the densities of liquids at intermediate temperatures which employs Archimedes Principle in a two-sinker arrangement. This method is then used to measure the densities of pure liquid calcium, strontium, and barium. We find ρ(Ca) = 1.4931-1.37 x 104T(°C) from 850-950°C, ρ(Sr) = 2.5547-2.83 x 104T(°C) from 780-880°C, and ρ(Ba) = 3.5561-2.99 x 104T(°C) from 730-830°C, where the units are gm/cm3. We use relations relating critical constants for these liquids to estimate dρ/dT, and compare these values of dρ/dT with those for other liquid metals; we also compare our results with recent x-ray diffraction data for these liquid metals.
