Thermodynamics of FeS-PbS-In2S3 and Properties of Intermediate Phases

The thermodynamic analysis and the X-ray Phase Analysis (XPA) of the FeS–PbS–In2S3 system were carried out. It is shown that along with the triple phases of MIn2S4 (M – Fe, Pb) and Pb6In6S21, the Fe1.5Pb5.5In10S22 phase also participates in the triangulation of the system. The standard thermodynamic...

Zusammenfassung:	The thermodynamic analysis and the X-ray Phase Analysis (XPA) of the FeS–PbS–In2S3 system were carried out. It is shown that along with the triple phases of MIn2S4 (M – Fe, Pb) and Pb6In6S21, the Fe1.5Pb5.5In10S22 phase also participates in the triangulation of the system. The standard thermodynamic functions for the formation of MIn2S4 (M-Fe, Pb), Pb6In6S21 and Fe1.5Pb5.5In10S22 are estimated. An isothermal section of the FeS–PbS–In2S3 system at 298 K is constructed. It is shown that the activation energy of the impurity level located in the band gap of Fe1.5Pb5.5In10S22 is equal to 0.19 eV.
