The 550 °C and 700 °C isothermal sections and new misfit layer compounds in the Se-Sn-V system

Abstract The phase relations of the ternary system Se-Sn-V was investigated over the whole composition range utilising powder X-ray diffraction (PXRD) and scanning electron microscopy (SEM) coupled with electron probe microanalysis (EPMA). The results of the evaluations in the ternary system are presented by two isothermal sections at 550 °C and 700 °C. A special focus was set on finding a misfit layer compound (MLC) in this system. Six MLCs are present at the compositions [(SeSn)1+δ]m(VSe2) (m = 1, 2, 3, 4, 5, and 6).
