Density and kinematic viscosity of NaF?ThF4 and KF?ThF4 melts

Thermodynamic properties and phase diagrams of fluoride salts for nuclear applications

“…The viscosity of liquid LiF-BeF 2 has been measured by Cohen and Jones [21] and Abe et al [22] for the compositions (31 and 32.8 mol% BeF 2 , respectively) as well as Blanke et al [18], Cantor et al [19] and Desyatnik et al [23] for a wide(r) range of compositions and temperatures. The agreement between the studies is excellent as is shown in Fig.…”

Evaluating physical properties of molten salt reactor fluoride mixtures

“…These properties may be predicted with a sufficient accuracy for the selected compositions, which is comparable with the experimental error. The calculation was made using known experimental values of the density [31][32][33][34][35], the dynamic viscosity [25,[36][37], the isobaric heat capacity [38], and the thermal conductivity [39][40][41] of molten fluorides of alkali metals, their mixtures, and LiF-MeF 4 and NaF-MeF 4 melts. Those values were determined by reliable experimental techniques: hydrostatic weighing (r), damped oscillations of a pendulum (h), high-temperature calorimetry (c p ), and coaxial cylinders (l).…”

“…By now the density of binary LiF-NaF [31], LiF-BeF 2 and NaFBeF 2 [32], LiF-ZrF 4 and NaF-ZrF 4 [35], LiF-ThF 4 and NaF-ThF 4 [33,34] melts was measured as a function of the temperature and the composition. Those data were used as the basis for calculating the density of the molten 0.18LiF-0.58NaF-0.24BeF 2 and 0.72LiF-0.21BeF 2 -0.07ZrF 4 mixtures with various model assumptions.…”

Thermal and physical properties of molten fluorides for nuclear applications

“…Numerous studies exist on the binary subsystems, especially on LiF-BeF 2 , considering several aspects, as phase behavior [1][2][3][4][5][6], density [7,8] and viscosity [8,9]. However, studies on the characteristics of the ternary systems are scarce.…”
