Density and surface tension of title mentioned melts is measured by the method of maximum pressure in gas (argon) bubble depending on temperature. The results are obtained in the form of coefficients of linear equations. The molar volumes and their deviations from additive magnitudes are computed as well as the excessive molar volumes of ternary melt at 1200K. The concentration dependences of surface tension of fused mixtures NaF-NaCl-HfCl4 upon composition for 1200L are given
