“…Pure anhydrous uranium(IV) chloride was obtained by the method described in [4]. Manganese(II) chloride was prepared from commercial MnCl 2 (reagent grade, POCh, Gliwice, Poland) by passing a dry hydrogen chloride gas stream through the molten MnCl 2 for 24 h to remove both traces of moisture and products of hydrolysis, and then distilling under vacuum at 700 K.…”

“…The relation consisted in the phase equilibrium type depending quantitatively on the ionic potentials ratio (l 1 /l 2 ) of both the component cations (1 and 2) of the system [1,2], the ionic potential l i of a cation ÔiÕ being defined [3] as a ratio of the cation charge (e i ) and its radius (r i ): l i = e i /r i . The dependence has been comprehensively demonstrated in [1] using the MCl n -UCl 4 ÔfamilyÕ of systems (where M is any metal) as an example. It appeared that the system types changed in sequence:…”

“…Studies on the phase equilibria in the T12Te-Bi2Te 3 system were effected mainly by means of cooling curve determination and, in some doubtful cases, with the heating curve technique too, in the apparatus for cryometric measurements described in [15]. The phase transition temperatures were measured as in investigations of the T12Te-Ag2Te system [16].…”

The phase equilibria in the TI2Te-Bi2Te3 system were studied by means of cooling curve determination, differential thermal analysis and X-ray diffraction methods; the results obtained with the former two methods were compared, The phase diagram established for the system differed considerably from three others published previously.The T12Te-Bi2Te3 system is one of the possible sections of the ternary TI-Bi-Te system, the phase diagram of which is unknown, although different alloys containing thallium, bismuth and tellurium have already been studied many times. The considerable interest in these alloys is caused by the fact that their components form ternary compounds with semiconductive properties. From among them, the compound TIBiTe 2 is of some importance in studies on semiconductivity [1], yet it is still unknown whether the compound melts congru6ntly or incongruently.The following sections of the TI-Bi-Te system have been investigated so far: Bi2Te3-TIzTe3 [2-5], Bi2Te3-TI [6,7], (50% T1 + 50% Bi/Te [8], BiTe-T1Te [9], BizTe3-T19BiTe6 [10], T12Te-Bi2Te 3 [11,12] and TI2Te-Bi2Te3-Te [13]. The phase equilibria in systems of the type TlzXW-BVX w have been discussed in [14]; it has been found that with increase in atomic weight of an element in Group V or VI of the periodic table, the number of compounds decreases in the succeeding system. For example, if four compounds are formed in the TI2S As2S 3 system, then only one congruently melting compound, of formula T1BiTe2, should be expected in the TI2Te-BizTe 3 system.The investigation results published to date on the TI2Te-Bi2T % system [10-12] differ considerably from one another (the Bi2Te3-TigBiTe 6 system [10] constitutes 90% of the TlzTe-Bi2Te 3 system). In two of these papers [11,12], it has been reported that the alloys rich in Bi2Te 3 form a limited solid solution. According to [10]

“…The phase diagram for the system under investigation has been delineated by using experimental points obtained by TA only in the cryometric apparatus described in [7]. The phase transition temperatures were determined similarly as in the studies on the T12Te-Ag2Te system [1], i. e. by means of a thermopile Pt/Pt, Rh calibrated at the freezing points of standards: Pb, Zn, PbC12, A1, KC1 and Ag.…”

The phase equilibrium diagram for the TI2Te-SnTe system has been established by thermal analysis (cooling curve method) and differential thermal analysis. The results obtained are compared with the other data.The present work is a part of the series of our studies on phase equilibria in the telluride systems of the type T12Te-MxTey, in which ternary compound formation may be expected with probable advantageous semiconductive properties. Up to now, systems have been investigated, the second component of which were the tellurides of following metals (M): Ag [1], Bi [2] and Sb [3].The T12Te-SnTe system is one of the possible sections of the ternary T1-Sn-Te one. The phase equilibria in the last system were studied earlier [4,5]. In paper [4] the phase diagram for the TI2Te3-SnTe system was given, while in [5] -the results of phase studies on eight different sections of the T1-Sn-Te system, among them also the phase diagram for the T12Te-SnTe one were presented. However, for the phase diagram of the latter different interpretations have been offered, and, on the other hand, it appeared to be inconsistent with our electrochemical studies by EMF measurements of concentration cells containing solid alloy (TI2Te + SnTe) electrodes [6]. Accordingly, we have again undertaken the phase studies on the title system by thermal analysis (employing the cooling curve technique, TA) and differential thermal analysis (DTA).
