Qısa məlumat

Alloys of the system Bi-Te obtained by long-term thermal annealing of samples quenched from 1000 K were studied by differential thermal analysis, x-ray phase diffraction, and scanning electron microscopy methods, as well as by electromotive forces measurements (EMF) of concentration cells relative to a bismuth electrode. A new refined version of the phase diagram which reflects the compounds Bi2Te3, Bi4Te5, Bi8Te9, BiTe, Bi4Te3, Bi2Te, and Bi7Te3 with practically constant compositions was constructed. It was found that all of these compounds, except for Bi2Te3, melt with decomposition by peritectic reactions. Based on powder diffraction patterns, the types and parameters of the crystal lattices of these compounds were determined. The EMF measurements were used to determine the partial molar functions of bismuth in the alloys and the standard integral thermodynamic functions of bismuth tellurides.
