Starting salts of purity grade cp were prepared; the hafnium fluoride was purified by double vacuum distillation. Experimental data were reduced using the method of least squares; results are presented for the measurements of the density of the fused mixtures of the KF-KCl-HfF/sub 4/. The highest concentration of hafnium fluoride in the mixtures was limited to 50 mole % due to the increase in the compressibility of its vapor. The density of the fused KF-KCl-HfF/sub 4/ salt mixtures increased with increased hafnium fluoride content. The concentrational dependence of the excess molar volumes is complex and indicates that on mixing the three components in the fused state, the interaction among the components is more complicated than for gas-phase interactions.
