“…The field boundaries (L + V) at atmospheric pressure (101.325 kPa) and in a vacuum (0.9 kPa) (shaded) are plotted on the phase diagrams (Figure 2). in this particular system for alloys that are rich in antimony selenide, as shown in the known phase diagrams [30,33], is not correct. However, it will not cause technological difficulties: the vapor phase is almost completely represented by selenium.…”

“…In a more recent study [ 30 ], the authors obtained a set of self-consistent thermodynamic parameters of the S–Sb binary system and the Cu–S–Sb ternary system using the so-called CALPAD method of the associated model of liquid solutions. Based on the obtained data, they calculated the delamination regions of liquid solutions in the Sb–Sb 2 S 3 and Sb 2 S 3 –S partial systems.…”

“…Thus, in [ 20 , 31 , 32 ], the thermodynamic activity of selenium was found and calculated for a temperature of 994 K (721 °C), which is higher than the boiling point of solutions of this composition. In [ 30 ], the top of the dome of the two-phase liquid system Sb 2 S 3 –S corresponds to a temperature of ~1417 K (1144 °C) (determined by us graphically). The latter is erroneous, since the boiling point of sulfur does not exceed 703 K (430 °C), and the field of liquid solutions on the state diagram below the boiling point of sulfur is practically degenerate.…”

The authors conducted liquid solution studies of antimony with selenium and sulfur in order to provide information on the thermodynamic functions of the formation of these alloys. The studies are based on the vapor pressure values of the components, comprising the double partial systems of antimony with antimony chalcogenides (Sb2Se3 and Sb2S3) and antimony chalcogenides with chalcogens (Se and S). We calculated the thermodynamic functions of mixing (graphical dependencies) and evaporation (tabular data) based on the partial vapor pressure values of components, which are represented by temperature–concentration dependencies. Based on the partial pressure values of melt components, we calculated the boundaries of liquid and vapor coexistence fields at atmospheric pressure (101.3 kPa) and in a vacuum (0.9 kPa). We established the absence of the stratification region on the Sb2S3–S diagram due to the fact that, on state diagrams, the stratification region is indicated at temperatures above 530 °C, while the boiling point of liquid sulfur at an atmospheric pressure corresponds to 429 °C. Based on the position of the field boundaries (L + V) on the state diagrams, the separation of antimony alloys with selenium and sulfur via distillation into elements at atmospheric pressure is difficult due to the high boiling points of antimony-based alloys in a vacuum: Sb2Se3–Se melts require some number of condensate re-evaporation cycles.

“…The Cu–Sb–S system includes four main phases (Figure S1): tetrahedrite (Cu 12 Sb 4 S 13 ), famatinite (Cu 3 SbS 4 ), skinnerite (Cu 3 SbS 3 ), and chalcostibite (CuSbS 2 ) . Among these phases, tetrahedrite Cu 12 Sb 4 S 13 is widely studied for thermoelectric applications due to its intrinsically low thermal conductivity. , Tetrahedrite Cu 12 Sb 4 S 13 has a space group of I 43 m ; its unit cell contains 58 atoms, and there are five crystallographically distinct atomic sites: Cu(1), Cu(2), S(1), S(2), and Sb.…”

In the present work, tetrahedrite Cu12Sb4S13 thin films were deposited on various substrates via aerosol-assisted chemical vapor deposition (AACVD) using diethyldithiocarbamate complexes as precursors. A buffer layer of Sb2O3 with a small lattice mismatch to Cu12Sb4S13 was applied to one of the glass substrates to improve the quality of the deposited thin film. The buffer layer increased the coverage of the Cu12Sb4S13 thin film, resulting in improved electrical transport properties. The growth of the Cu12Sb4S13 thin films on the other substrates, including ITO-coated glass, a SiO2-coated Si wafer, and mica, was also investigated. Compared to the films grown on the other substrates, the Cu12Sb4S13 thin film deposited on the SiO2-coated Si wafer showed a dense and compact microstructure and a larger grain size (qualities that are beneficial for carrier transport), yielding a champion power factor (PF) of ∼362 μW cm–1 K–2 at 625 K. The choice of substrate strongly influenced the composition, microstructure, and electrical transport properties of the deposited Cu12Sb4S13 thin film. At 460 K, the highest zT value that was obtained for the thin films was ∼0.18. This is comparable to values reported for Cu–Sb–S bulk materials at the same temperature. Cu12Sb4S13 thin films deposited using AACVD are promising for thermoelectric applications. To the best of our knowledge, the first full thermoelectric characterization of the Cu12Sb4S13 thin film is performed in this work.

“…Zhang et al [4] suggested that the addition of Cu accelerated the formation of corrosion products and increased the corrosion current density, and Cu improved the long-term protection of rust layer by forming CuFeO 2 . There was an interaction between Cu and Sb [5,6]. Wu et al [7] added Cu and Sb with different contents into 3Ni steel, and found that there was a synergistic effect between 0.5% Cu and 0.2% Sb, which improved the corrosion resistance of 3Ni steel.…”
