“…If we take gAx = gAX, gxx = rgxx, and gsx = g~x, there is a contradiction between [11] and [12]. Our previous work (4) showed that reasonable surface tensions could not be obtained if the local electroneutrality condition, a consequence of the long range of the Coulomb interaction, was not satisfied.…”

“…As a function of composition, the surface tension varies smoothly, so that a prediction of the surface tension of the equimolar mixture (plus knowledge of surface tensions for the pure components) probably gives all the information needed. Bertozzi (12) has measured surface tensions for mixtures of these salts at 800°C (1073°K). In order to minimize the effects of experimental errors, we use his values of surface tension (read offhis plots), for the pure salts as well as the mixtures, in our calculations: YNaCl = 118.5 dyn/cm, YKcl = 99.5 dyn/cm, Yeq = 106.5 dyn/cm.…”

It is always found that the surface tension of a mixture of molten salts lies below the mean of the surface tensions of the pure components, weighted by mole fractions. Part of this effect is certainly due to the well-known fact that the composition near the surface is enriched in the component of lower surface tension. We show that an effect of the long-range forces, present for fluids involving Coulombic interactions, is of greater importance. The effect is due to the electroneutrality constraint on the distribution functions. As we show by separate calculations, both effects must be considered to obtain good agreement with experimental results for alkali halide melts.

“…In a series of studies of the surface tension of binary molten salt systems, Bertozzi (14,23,24) advocated the use of the semiempirical expression -~ : x1~i + x2~2 --#xix2 [1] to represent the data. In this equation xi is the mole fraction of component i, "Yi is the surface tension of pure component i, and # is a constant which may be empirically determined.…”

Surface tension measurements are reported for the binary molten salt system normalLiCl‐normalKCl over the composition range 10–90 mole per cent normalKCl and at temperatures ranging from the melting point to 850°C. All measurements were made using the maximum bubble pressure method. The surface tension is linearly dependent on temperature, and the experimental results for the mixture at constant temperature are best explained on the basis of regular solution behavior. However, there is an indication that some local structure exists in the melt.
