“…Actually, the classical hypotheses of the IMCT 30,31,[34][35][36][37][38][39][40][41] are to some degree similar with those of the associated solution model, [70][71][72][73][74][75] especially the ideal associated solution model. 70,71 The defined N i of the structural unit i or ion couple (Me 2þ þ O 22 ) in slags by equation (3) based on the IMCT looks like the defined activity a R, i by the molecular theory.…”

Thermodynamic models for predicting phosphorus distribution ratio P and phosphate capacity C PO 32 4 of CaO-FeO-Fe 2 O 3 -Al 2 O 3 -P 2 O 5 slags during secondary refining process of molten steel, according to the ion and molecule coexistence theory (IMCT), i.e. IMCT2 P and IMCT2C PO 32 4 4 against the aforementioned parameters can be observed for the slags in the higher temperature range from 1918 to 1927 K. The influences of the aforementioned parameters on dephosphorisation ability are significantly different from those on dephosphorisation potential of the slags.

“…These models enable us to describe the thermodynamic functions taking into account the existence of short range order phenomena in metallic melts that is often indicated by a pronounced asymmetry of the corresponding curves describing concentration dependences [1][2][3][4][5][6][7][8][9][10].…”

The thermodynamic activities, the excess integral and partial Gibbs energies, and the enthalpy of mixing for Bi-In melts were studied. For investigation, the methodology of thermodynamic modeling (TM) including the models of an ideal solution (IS) and an ideal solution of interaction products (ISIP) was applied. The modeling was performed for the pressure of 0.1 MPa in an argon atmosphere. The temperature and concentration ranges of study comply with liquid phase region on the Bi-In phase diagram. It has been established the thermodynamic properties of Bi-In melts show negative deviations from Raoult's law. The mixing enthalpy minimum was observed at x(In) = 0.55 and ∆H E = -1.33 kJ mol −1 . In the present study, the lowest values of the excess integral Gibbs free energy were determined as -1.80 and -1.99 kJ mol −1 at the temperatures 600 and 873 K, respectively.K e y w o r d s : Bi-In system, melt, enthalpy of mixing, activity, Gibbs energy, associates

“…The general thermodynamic description of the model of associated solutions without specifying the objects is given in monographs by Prigogine and Defay [62] and Prigogine [63]. Application of models of associated solutions to liquid metal systems is discussed in numerous papers [23,31,48,[64][65][66][67][68][69][70][71][72][73][74][75][76][77].…”

Published data on thermodynamic properties, structure, and applications of liquid mercury-sodium alloys are discussed. 115 years ago, N.S. Kurnakov published in Russian, German, and French chemical journals the fi rst and, at the same time, the basic paper, "On Mutual Compounds of Metals" [1]. In this paper, he analyzed the results of studying the phase diagrams of sodium and potassium amalgams and of sodium alloys with cadmium, lead, and bismuth. Such previously unknown compounds as HgNa and Hg 2 Na were discovered. Their existence could not be rationalized from the standpoint of the classical valence theory. Kurnakov noted: "…Alkali and alkaline earth metals exhibiting the most pronounced base or metal properties show particularly pronounced tendency to form compounds. Their combinations with Hg, Zn, Pb, Sn, Cd, Bi, and other heavy metals are undoubtedly the most characteristic and the best defi ned group of mutual combinations of metals known by now. As could be expected from the position of alkali metals in the periodic table, this group is characterized by extraordinary diversity of forms" [1].Paper [1] initiated broad-scale studies of variablecomposition phases in metal systems in Russia. In subsequent papers, Kurnakov and his closest coworkers and disciples formulated the concept of bertollides and daltonides, developed the doctrine of compositionproperty diagrams, and laid the groundwork for a major section of general chemistry, physicochemical analysis [2][3][4].The logical continuation of studies on phase diagrams of metal systems was studying the nature, thermodynamic properties, and structure of liquid alloys. Such studies were performed particularly actively in the second half of the XX century. Liquid mercury-sodium alloys fi nd diverse applications in technology, which has been noted in a number of special monographs [5][6][7][8][9]. The production of chlorine and alkali by electrolysis with a liquid mercury cathode remains an important application fi eld of sodium amalgam [7,10]. Certain problems related to the use of sodium amalgam are discussed in the concluding part of this review.According to published data, mercury forms with sodium a congruently melting compound Hg 2 Na (mp 353°C) and a series of compounds melting with decomposition
