“…Due to this slight difference in symmetry of the octahedra, a partial ordering of the cations has been reported in the literature with a preference of bismuth for the 6c site and of A IV for the 3a site (however, this ordering is only a partial ordering with mixed occupancy on the two sites) [14]. However, a previous report showed that the XRD patterns refinements are further improved by allowing the cations to partly occupy the interlayer spacing (3b site), although no further evidence of this partial occupancy, which resulted in very large thermal displacement parameters, was provided [20].…”

“…The lattice parameters of SnBi 2 Te 4 and PbBi 2 Te 4 reported in the literature slightly differ from one publication to another (see Refs. [11,14,20] and ref. therein), which could probably be explained by different actual stoichiometry or different cations mixing due to different synthesis processes.…”

“…Similar difficulties in the Rietveld refinement of SnBi 2 Te 4 had already been reported in Refs. [14,20]. Therefore, we chose to perform LeBail refinement within the R3m space group, as the determination of the actual sites occupancy for mixed (Pb/Sn) Bi 2 Te 4 should be even more complicated.…”

“…While the Sn-Bi-Te phase equilibria are very important, only very limited relevant results are available. [9][10][11][12][13][14][15] The phase diagrams of its three binary constituent systems, Sn-Bi, Sn-Te, and Bi-Te, have been studied. 16,17 Both Sn-Bi and Sn-Te systems are fairly well understood.…”

Bi 2 Te 3 is one of the most promising thermoelectric materials, and Sn is the primary constituent of most electronic solders. Knowledge of phase equilibria of the Sn-Bi-Te ternary system is important for thermoelectric applications. Twenty-seven Sn-Bi-Te alloys were prepared and equilibrated at 160°C and 500°C. The equilibrium phases were determined, and the isothermal sections were constructed based on three binary constituent phase diagrams and ternary phase equilibria results. No ternary compounds were observed in the Sn-SnTe-Bi region. The SnTe phase is very stable and has tie-lines with the Sn, liquid, and Bi phases at 160°C. At 500°C, in addition to the already known SnBi 2 Te 4 and SnBi 4 Te 7 ternary phases, two new ternary compounds (Sn 2 Bi 2 Te 5 and SnBiTe 2 phases) were found. SnTe and Bi 2 Te 3 have significant mutual solubilities, and the ternary compounds SnBi 2 Te 4 , SnBi 4 Te 7 , and Sn 2 Bi 2 Te 5 are all in the SnTe-Bi 2 Te 3 pseudobinary section.

“…In this context, we have investigate the SnX-Bi 2 X 3 (X = S, Se, Te) systems and we report here the results on the SnSe-Bi 2 Se 3 system. Collected data on SnTe-Bi 2 Te 3 and SnTe-Bi systems have been reported elsewhere [8].…”
