Antimony thermodynamic propertie

The phase diagram and the thermodynamic properties of the liquid phase in the antimony-selenium system were assessed by Ghosh, Lukas, and Delaey [89GHO/LUK] and by Ghosh [93GHO]. Sb2Sc3(cr) is the only intermediary compound in the system.

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 thermodynamic properties were determined of AlSb -GaSb solid solutions, with 10 at.excess antimony, by measuring the electromotive forces of the galvanic cells lAISb, Sb, CaAlFs, CaP2 ICaFj (A1, Ga)Sb, Sb, CaAlFs, CaFjl at 855 Negative deviations from Raoult s law were found.

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. 

This volume of the Handbook illustrates the rich variety of topics covered by rare earth science. Three chapters are devoted to the description of solid state compounds skutteru-dites (Chapter 211), rare earth-antimony systems (Chapter 212), and rare earth-manganese perovskites (Chapter 214). Two other reviews deal with solid state properties one contribution includes information on existing thermodynamic data of lanthanide trihalides (Chapter 213) while the other one describes optical properties of rare earth compounds under pressure (Chapter 217). Finally, two chapters focus on solution chemistry. The state of the art in unraveling solution structure of lanthanide-containing coordination compounds by paramagnetic nuclear magnetic resonance is outlined in Chapter 215. The potential of time-resolved, laser-induced emission spectroscopy for the analysis of lanthanide and actinide solutions is presented and critically discussed in Chapter 216.
