The authors studied the density rho and the surface tension rho of the four-component LiF-BeF/sub 2/-ThF/sub 4/-UF/sub 4/ system in a wide temperature range. The concentration range of the molten salts corresponds to salt compositions with a low melting point and a rather high concentration of fissile materials. In the three-component LiF-BeF/sub 2/-ThF/sub 4/ system, compositions in the following concentration range were selected (expressed as molar fraction, %): ThF/sub 4/ ( less than or equal to 20) and BeF/sub 2/ (less than or equal to 40). Uranium tetrafluoride was added up to a maximum concentration of 40% to the melts. The results of the rho and sigma measurements were evaluated with the least-square method. The temperature dependencies of the properties studied in the 32 compositions examined are quite adequately described by linear equations.
