Only BiTeCl exists as a ternary phase in this system. The compound melts incongruently at 430 °C. The heat of formation and the standard entropy of BiTeCl were calculated from vapor pressure data: AH°b (BiTeCl, f, 298) = (-39,5 ± 1,6) kcal/mol; S° (BiTeCl, f, 298) = (34,4 ± 2,7) cal/K mol. The heat of formation of BiCl3 was determined on the basis of the heat of solution of BiCl3 and Bi20 3, and the heat of formation of Bi20 3: z\Hß (BiCl3, f, 298) = (-95,9 ± 0,9) kcal/mol. | | | |
