Chumak I. Phase equilibria and crystal structure of the compounds in the {Fe,Ni}-Zn-{Si,Ge,Sb,Bi} systems

In this work by means of X-ray phase, X-ray structure, thermal and local X-ray spectral analysis components interaction in {Fe,Ni}-Zn-{Si,Ge,Sb,Bi} ternary systems were investigated, isothermal sections of state diagrams at 570 K were built. 10 of 17 ternary compounds that form in investigated systems were found at first and structurally investigated. New structure type Ni3ZnSb2 was found and described. Structure of binary compound FeSb2 was obtained using single crystal technique and we have shown that it belongs to FeS2 structure type, but no to it's own, as was reported in literature. Thermodynamic modeling for ternary system Fe-Zn-Si was carried out using PANDAT program package and it's result is in good correlation with experimental data.
