Abstract
The phase diagram of the pseudobinary sytem Bi2Te3/BiBr3 was investigated by DTA, total pressure measurements and X-ray phase analysis. Only BiTeBr exists as a ternary phase in this system. The compound melts congruently at 526 °C. The heat of formation and standard entropy were calculated from vapor pressure data:
ΔH(BiTeBr, f, 298) = (-30,4 ± 1,4) kcal/mol; S°(BiTeBr, f, 298) = (36,2 ± 2,9) cal/K·mol.
