Densities of Fe-P alloys were measured accurately by the improved sessile drop method. Photographs of sample were taken from three directions by three cameras which were installed at the same angle of 120° on the horizontal plane. From the image on the film, the volume of the samples was calculated by means of an auto-scanning type instrument of length measurement. The average value of the volume calculated from the photographs taken from the three directions was used for the calculation of the density of the sample. The obtained relations between density and temperature were as follows : [numerical formula] where ρ(s), ρ(l) and σ indicate the densities in the solid and the liquid states and the standard deviation respectively. From the results of the experiment, it was concluded that the state of bonding in the liquid state was similar to that in the solid state in the range of concentration of phosphorus of 5 to 10 wt%.DensityIronPhosphorusAlloySolid phaseLiquid phaseVolume changeThermal expansion
