Qısa məlumat

The Tl-Sb-Se system is studied by differential thermal analysis, X-ray diffraction analysis, by microhardness measurements, and by measurements of the electromotive force of electrolyte-concentration cells. The TlSbSe2-Se(Tl) and TlSe(Tl3Sb)-Sb2S3 vertical sections, the projection of the liquidus surface on the composition triangle, and the 300 K level section of the phase diagram are constructed. Chemical compounds Tl9SbSe6, Tl3SbSe3, TlSbSe2, and TlSb3Se5 and an extended Tl2-xSe-Tl9SbSe6 solid solution are found to exist. The existence of the Tl4SbSe2, Tl3SbSe2, Tl2SbSe2, Tl6Sb8Se13 compounds reported in earlier publications is not confirmed. The standard thermodynamic functions of formation of Tl3 SbSe3 are determined.
