Phase equilibria and new misfit layer compound in the ternary system of Pb–Se–V

Abstract The ternary system Pb–Se–V was investigated by means of powder X-ray diffraction (PXRD), scanning electron microscopy (SEM) in combination with electron probe microanalysis (EPMA), and differential thermal analysis (DTA). The results of the evaluations in the ternary system are presented by five full isothermal sections at 550 °C, 700 °C, 800 °C, 1000 °C, and 1100 °C and one partial isothermal section at 375 °C. A special focus was set on finding a misfit layer compound (MLC) in this system. With the phase (PbSe)1+δ(VSe2) one MLC can be reported.
