“…The bright phase is the Sn 3 Sb 2 phase and the matrix region was the liquid phase prior to quenching. According to the phase diagrams by Hansen and Anderko 8 and Vassiliev et al, 10 alloy #01 is also in a L + solid two-phase field. However, their phase diagrams 8,10 do not have the Sn 3 Sb 2 phase, and the bright phase is the b-SnSb phase.…”

“…The phase diagram of the Sn-Sb system has been investigated by various groups. [8][9][10][11][12][13][14][15][16] However, the phase boundaries at temperatures lower than 250°C have not been determined and the available phase diagrams [8][9][10] are not consistent. One compound, b-SnSb, with large compositional homogeneity range and an order-disorder transformation was proposed by Hansen and Anderko.…”

“…8 In addition to the b phase, Predel and Schwermann 9 proposed another compound, Sn 3 Sb 2 , which was stable only within a small temperature range. Vassiliev et al 10 suggested four compounds, b, b¢, b¢¢, and b¢¢¢, in the Sn-Sb binary system.…”

“…[8][9][10] This study experimentally determined the phase diagram of the binary Sn-Sb system focusing on resolving the differences in the available phase diagrams, and also establishing the phase boundaries which have not been determined previously. The phase equilibrium results determined in this study and the thermodynamic and phase equilibrium data in the literature are then used together for thermodynamic modeling using the CALPHAD approach.…”

Sn-Sb alloys are important high-temperature solders. However, inconsistencies are found in the available phase diagrams, and some phase boundaries in the Sn-Sb system have not been determined. Sn-Sb alloys were prepared, equilibrated at 160°C to 300°C, and the equilibrium phases and their compositions were determined. The b-SnSb phase has a very wide compositional homogeneity range, and its composition varies from Sn-47.0at.%Sb to Sn-62.8at.%Sb. There is no order-disorder transformation of the b-SnSb phase. There are three peritectic reactions in the Sn-Sb system, L + Sb = b-SnSb, L + b-SnSb = Sn 3 Sb 2 , and L + Sn 3 Sb 2 = Sn, and their temperatures are 424°C, 323°C, and 243°C, respectively. Thermodynamic models of the Sn-Sb binary system were developed using the CALPHAD approach based on the experimental results of this study and the data in the literature. The calculated phase diagram and thermodynamic properties are in good agreement with the experimental determinations.

“…Nous avons réalisé, essayé et utilisé sur différents alliages trois types de piles en'Pyrex', dont la conception nous est propre. L'un des trois convient bien jusqu'à 200C [1][2][3] et les deux autres fonctionnent aux températures plus élevées, jusqu'au ramollissement du'Pyrex' (560-600°C) [4][5][6][7][8][9]. On peut également exploiter les mêmes types de constructions, en verre réfractaire ou en quartz, jusqu'à 1000°C [10].…”

: This paper reviews some methodological problems and experimental sources of errors which are encountered when using electrochemical cells with liquid electrolytes to determine thennodynamic properties of alloys. Indications to get reliable results are given. INTRODUCTIONLa méthode de mesure des forces électromotrices (FEM) de piles à électrolyte liquide est un instrument puissant pour étudier les propriétés thermodynamiques des systèmes métalliques et semi-conducteurs. Elle permet de déterminer un ensemble de valeurs du potentiel chimique de l'un des composants dans les différentes phases du système étudié. Le résultat final de ce travail consiste à optimiser numériquement le système du point de vue thermodynamique.Nous envisageons dans cette communication certains problèmes méthodologiques et les sources d'erreurs qui apparaissent lors des mesures de FEM des piles électrochimiques et les moyens de les surmonter. 1 Principe de la méthodeOn réalise des mesures de potentiel aux bornes de cellules électrochimiques, avec électrolyte liquide, du type : (1) x représente la fraction molaire du composant A dans l'alliage liquide ou solide AxB (l-x).Le composant A (en général un métal pur) constitue l'électrode négative, l'alliage AxB (l-x) dans lequel le composant B est plus noble que A, constitue l'électrode positive. Le potentiel chimique du AptA=RTLn(a(A) (2) A Auna est la variation du potentiel chimique du composant A entre le metal pur et l'alliage Arbi-x dans les conditions de référence. La mesure de E en fonction de la temperature mène aux fonctions thermodynamiques partielles.

The isothermal cross‐section through the ternary phase diagram Sn‐Ag‐Sb at 220°C was constructed by means of diffusion couples and equilibrated alloys. It is proposed that only two phases, Sn4Sb3 and Sn3Sb4, exist in the binary Sn‐Sb system, and no equi‐atomic compound SnSb is present as an equilibrium phase at this temperature. No ternary phases were found in the Sn‐Ag‐Sb system at 220°C; the topology of the isotherm is largely determined by the presence of the extended region of solid solution between the ζ‐Ag4Sn and ζ‐Ag4Sb intermetallic phases.
