“…[4]). In our previous work [6] we have derived expressions of how to use different ion intensity ratios (e.g., Ag + to In + or Ag + to Sn + ) independently for the least-squares determination of the theoretically same ternary Ls and the thermodynamic properties. Applying these expressions to the Al-Cu-Sn system the following equations are obtained using the Al + to Sn + ion intensity ratio, called as 'Al + /Sn + method':…”

“…Also, if the volatility of a component is much higher (i.e., orders of magnitude,) than that of the other ones this method does not require the measurement of the mass spectrum or the analysis of the vapour deposit (see Refs. [5,6]) if only the activity of the volatile component is required. Nevertheless, if the volatility of one of the components is much higher than that of the others, the rate of compositional shift can be such that shorter evaporation times are necessary in order to avoid fast distillation.…”

“…Recently, we applied Miki's [4] method to the study of the Cu-In-Sn system using only the Cu + to Sn + ion intensity ratio but we supplemented Miki's method assuming the classically three different ternary interaction parameters [5]. Later, in studying the Ag-In-Sn system [6] our aim was to elaborate on equivalent mathematical regression procedures using both the Ag + to Sn + and the Ag + to In + ion intensity ratios as independent input data, in order to study the mathematical relationship between the procedures based on both ion intensity ratios. In addition, we compared the data obtained by both procedures and in doing so confirmed the reliability of the data using the standard, model-free KEMS procedures.…”

Keywords:Knudsen effusion mass spectrometry Redlich-Kister-Muggianu model Activity Excess Gibbs energy Ternary and binary L-parameter a b s t r a c tThe vaporisation of a liquid Al-Cu-Sn system has been investigated at 1273-1473 K by Knudsen effusion mass spectrometry (KEMS) and the data fitted to a Redlich-Kister-Muggianu (RKM) sub-regular solution model. Thirty-one different compositions (41 samples) have been examined at eight fixed copper mole fractions, X Cu = 0.10, 0.20, 0.30, 0.333, 0.40, 0.50, 0.60 and 0.70. The ternary L-parameters, the thermodynamic activities and the thermodynamic functions of mixing have been evaluated using standard KEMS procedures. In addition, the same quantities were obtained from the measured ion intensity ratios of Al + to Cu + , Al + to Sn + and Cu + to Sn + using a mathematical regression technique. The intermediate data obtained directly are the RKM ternary L-parameters that are, as a function of temperature, as follows:(0) = (14270 ± 1270) + (100.1 ± 7.6)T − (11.77 ± 0.93)T ln(T ); L (1) = (145600 ± 9780) + (101.6 ± 58.7)T − (15.56 ± 7.14)T ln(T ); L (2) = (76730 ± 1240) + (79.2 ± 7.4)T − (15.69 ± 0.91)T ln(T ).From the obtained ternary L-parameters the integral molar excess Gibbs energy, the excess chemical potentials, the activity coefficients and the activities have been evaluated. Using the temperature dependence of the activities, the integral and partial molar excess enthalpies and entropies can be also determined. In addition, for comparison, for some compositions, the Knudsen effusion isothermal evaporation method (IEM) and the Gibbs-Duhem ion intensity ratio method (GD-IIR) were used to determine activities and good agreement was obtained from the RKM model.

“…In contrast to binary alloys, there is a lack of thermodynamic data concerning ternary alloys. Our former KEMS studies on Cu-In-Sn [1], Ag-In-Sn [2], Al-Cu-Sn [3], Cu-Sb-Sn [4] liquid ternary systems in the framework of the EU's COST 531 and MP0602 actions could improve this circumstance, at least to some extent. In 2001 Miki et al, [5] were able to show that by using the Redlich-Kister-Muggianu (RKM) sub-regular solution model for liquid alloys they could obtain the ternary interaction parameters directly from mass spectrometric measurements.…”

We discuss the vaporisation of four liquid ternary-alloy systems, namely, Cu-In-Sn, Ag-In-Sn, Al-Cu-Sn and Cu-Sb-Sn, on the basis of our previous Knudsen effusion mass spectrometric (KEMS) investigations of these systems. The thermodynamic activities and the thermodynamic functions (Gibbs energy, enthalpy, entropy) of mixing were determined using selected standard KEMS procedures (i.e., Simple Pressure Calibration Method (SPC), Oligomer Composition Change Method (OCC), Isothermal Evaporation Method (IEM) and Gibbs-Duhem Ion Intensity Ratio Method (GD-IIR)). In addition, the same thermodynamic quantities, as well as the so-called ternary interaction (L-) parameters, were also obtained from the composition dependence of the measured ion-intensity ratios using a new mathematical procedure (RKM-KEMS). The essence of this new procedure is the fitting of the measured intensity-ratio data were to the Redlich-Kister-Muggianu (RKM) sub-regular solution model, and this model is valid for many liquid ternary alloys, including the systems reviewed here. A full description of the mathematical derivation of RKM-KEMS is given in this work. The primary and intermediate data, obtained directly from the multiple-regression as output data, are the RKM ternary interaction L-parameters. From these quantities, the integral molar excess Gibbs energy, the excess chemical potentials, the activity coefficients and the activities were evaluated in this order. In addition, using the temperature dependence of activities, the integral and partial molar excess enthalpies and entropies could also be determined. The thermodynamic data obtained with the above-mentioned conventional KEMS methods and with the new RKM-KEMS procedure were compared and a good agreement was obtained for the systems studied.
