“…The parameters of the Gibbs energy of metals and the interaction parameters of the liquid and solid phases were taken from the COST531 ver. 3.1 data base [7]. In this database the assessment of the Bi-Zn system was based on Malakhov's system optimization [20] with an improvement of the new data for the solubility of Bi in the hcp-Zn terminal phase [21].…”

“…The thermodynamic modelling of Lee et al [22], with some amendments of the In-Zn interaction parameters of the binary solid phases, was adopted for the In-Zn system. According to the assessment of Vizdal et al [21], the datasets for the Bi-Sn and Bi-Sn-Zn systems were included in the COST531 database [7].…”

PHASE EQUILIBRIA IN THE Bi-In-Sn-Zn SYSTEM. THERMAL ANALYSIS VS. CALCULATIONSWith the use of the differential thermal analysis (DTA), studies of the phase transitions were conducted for 90 of alloys from the quaternary Bi-In-Sn-Zn system and for the constant ratio of Bi:In and Bi:Sn. The studies were conducted for the alloys prepared from the purity metals (Bi, In, Sn, Zn = 99.999 mas. %) by way of melting in a graphite crucible in a glove-box filled with Ar, in which the impurities level was less than 0.1 ppm. After melting and thorough mixing, the liquid alloys were poured out into a graphite test mold. The phase transition temperature data obtained from the DTA investigations were next confronted with those determined from the calculations based on the binary and ternary optimized thermodynamic parameters available in the literature. It was found that the experimental and the calculated phase transition temperatures were in good agreement.

“…The Ag-Sb, Ag-Sn, and Sb-Sn binary systems have already been thermodynamically assessed. 3 As far as the ternary system is concerned, literature data for the Ag-Sb-Sn system are rather scarce. However, all authors agree that no ternary intermetallic compounds were observed in the Ag-Sb-Sn system.…”

The thermodynamic properties of liquid Ag-Sb-Sn alloys were obtained through use of the drop solution calorimetric method and electromotive force (emf) measurements of galvanic cells with a yttria stabilized zirconia (YSZ) solid electrolyte. The experiments were carried out along Ag 0.25 Sb 0.75 , Ag 0.5 Sb 0.5 and Ag 0.75 Sb 0.25 sections of the ternary system in the temperature range from 973 K to 1223 K. From the measured emf, the tin activity in liquid solutions of Ag-Sb-Sn was determined for the first time. The partial and integral enthalpy of mixing were determined from calorimetric measurements at two temperatures. These measurements were performed along two crosssections: Sb 0.5 Sn 0.5 at 912 K and 1075 K, and Ag 0.75 Sb 0.25 at 1075 K. Both experimental data sets were used to find ternary interaction parameters by applying the Redlich-Kister-Muggianu model of the substitutional solution. Consequently, the set of parameters describing the thermodynamic properties of the liquid phase was derived.
