“…Considering the fact that Popović et al [12] experimentally obtained indium activity in this system at 1173 K, and the calculated values for the same are obtained by Milosavljević [13], it seems to be that the best agreement shows the Kohler method. Calculated values for indium activity by the Toop model [13] showed absolutely disagreement with experimentally obtained activities for the Cu-In-Sn alloys [12]. Therefore, it can be confirmed that the better one is symmetric type of predicted model.…”

“…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.…”

“…In addition, Miki et al [4] determined a single ternary L-parameter and the corresponding thermodynamic data of mixing by measuring only the ion intensities of Ag + and In + , i.e., only the Ag + to In + ion intensity ratio. 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.…”

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.

“…Li et al [21] determined the partial and integral enthalpies of mixing of liquid alloys at 800 • C by a drop calorimetric technique using a Calvet microcalorimeter, and constructed the corresponding iso-enthalpic curves at this temperature. Moreover Popovic and Bencze [22] measured the thermodynamic activities of all three components using Knudsen effusion mass spectrometry between 1000 and 1200 • C, while Jendrzejczyk-Handzlik et al [23] determined thermodynamic properties of liquid Cu-In-Sn alloys using solid oxide galvanic cells with zirconia electrolyte in the temperature range 700-950 • C.…”
