The surface tension and density of the LaCl3–NaCl system were determined as a function of temperature by the maximum bubble pressure technique. The surface tension and density were found to vary linearly with temperature (1123 < T < 1248 K). At constant temperature, the surface tensions of LaCl3–NaCl melts showed a small negative deviation from Guggenheim's Equation.

The maximum bubble pressure method was used to determine the surface tension and density of melts within the PbCl2–KCl–NaCl system. The temperature range of this study was from 450 to 800 °C. In all cases, the surface tension was found to decrease with increasing temperature. At constant molar ratios of KCl to NaCl, a minimum in the surface tension was observed at approximately 40 mol% PbCl2. The ternary surface tension values were found to obey the simple additivity expression of the binary surface tensions of PbCl2–KCl and PbCl2–NaCl. Based on these findings, constant surface tension contours have been drawn.The density obtained in the present study agree well with the previously determined densities using a bottom-balance Archimedean technique reported by this laboratory.

The surface tensions of methanol, acetone, dimethylformamide, dimethylsulfoxide, and methylamine over limited temperature ranges, and of solutions of alkali halides in the first three of these liquids at 25 °C have been measured by the method of maximum bubble pressure, with precautions against moisture. The data for the pure liquids are compared with literature data where these exist. The results for the solutions are discussed in the light of various existing theories.

The surface tensions of the molten binaries CaCl2-NaCl, LaCl3-NaCl, and LaCl3-CaCl2 and the three quasi-binaries LaCl3-nNaCl.mCaCl2 (mole ratios n : m = 2.7 : 1, 1 : 1, and 1 : 3.1) were measured by the maximum bubble pressure method. The surface tension of CaCl2-NaCl and LaCl3-CaCl2 increases curvilinearly with increasing CaCl2 concentration, while below 900 °C the isotherms of LaCl3-NaCl show a minimum at ca. 30 mol% LaCl3. A minimum was also observed for the quasi-binary with n : m = 2.7 : 1. The surface tensions for the ternary LaCl3-CaCl2-NaCl at 900 °C were constructed from the above results.

Abstract The surface tension around the eutectic composition of molten binary and ternary mixtures composed of Li2CO3 with Na2CO3 and/or K2 CO3 has been measured by the maximum bubble pressure method. The surface tensions of all the three systems were represented as functions of temperature
