Antimony, thermodynamic data

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. 

No thermodynamic data have been found for antimony selenites. 

Temperature-dependent thermodynamic standard data of an-timony(III)/antimony(V) redox equilibrium (Equation (26-28)), in an oxidic glass-forming silicate melt see also Figure 26-18. 

It has been demonstrated with a T-jump relaxation method, for instance, that in antimony pentachloride solutions, prepared with various donor solvents, there is a linear correlation between the rate of substitution by triphenylchloromethane of the donor solvent molecule bound at the sixth, free coordination site of the antimony and its donicity [Gu 71, Gu 72]. Both thermodynamic considerations and experimental data showed an analogous correlation between the rate of formation of CoClJ (by the interaction of C0CI3 and Cl ions dissolved in various donor solvents) and the Gutmann donicities of the donor solvents [Ma 75].
