摘要：
The Gibbs free energies, enthalpies and entropies of formation of bismuth selenide Bi2Se3 between 308 and 408 K, bismuth telluride Bi2Te3 between 308 and 413 K, and their solid solutions between 670 and 840 K are measured using the e.m.f. method. Positive deviations of the activities of components in the solid solutions from the ideal behavior are found. The possibility of ordering effects in the solid solutions at lower temperatures is assumed.
