The thermodynamic properties of the higher bismuth and antimony tellurides and selenides have been investigated by many authors but the results are contradictory. 

The electrolyte in the measurements of the thermodynamic properties of bismuth sele-nide and telluride and of antimony telluride was the easily melted mixture of anhydrous zinc chloride (analytic purity) with sodium and potassium chlorides (chemical purity grade). The melting point of this mixture was Tmp — 208 C. The thermodynamic properties of antimony selenide were determined using a mixture of aluminum chloride (distilled twice in vacuum) and sodium chloride (chemical purity grade). The meltii point of this mixture was Tmp = 150-155°C.

It follows from Tables 2 and 3 that the thermodynamic properties obtained in our investigation were in good agreement with those deduced using a solution calorimeter (the solvent was liquid bismuth at T = 623°K) [7] and with the values reported in [5] for bismuth and antimony tellurides, deduced by the emf method in the 643—683 K range. 

The high-temperature thermodynamic data obtained in the present study and in [5] were reduced to T — 298 K using the temperature dependence of the specific heat of bismuth telluride in the 550-28 C range [12], the thermodynamic properties of the elements [il], and the temperature dependences of the specific heat of Bi2Se3, Sb2Se3, and Sb2Te3 deduced in the —25°C...

The physical properties of bismuth, summarized ia Table 1, are characterized by a low melting poiat, a high density, and expansion on solidification. Thermochemical and thermodynamic data are summarized ia Table 2. The soHd metal floats on the Hquid metal as ice floating on water. GaUium and antimony are the only other metals that expand on solidification. Bismuth is the most diamagnetic of the metals, and it is a poor electrical conductor. The thermal conductivity of bismuth is lower than that of any other metal except mercury.
