Ternary chlorides in the systems ACl/HoCl3 (A = Cs, Rb, K)
Roffe,Seifert
, p. 128 - 133 (1997)
The phase diagrams of the pseudo-binary systems ACl/HoCl3 (A = Cs, Rb, K) were investigated by DTA and XRT. The existence of compounds A3HoCl6, Cs2HoCl5, Cs3Ho2Cl7 and AHo2Cl7 could be confirmed. Additionally, the 2:1-compounds Rb2HoCl5 (Cs2DyCl5-structure) and K2HoCl5(K2PrCl5-structure) were found. By solution enthalpy and e.m.f vs. T measurements in galvanic chlorine cells for solid electrolytes, the thermodynamic functions for the formation from ACl and HoCl3 and for the formation from the compounds adjacent in the phase diagrams were measured. The compounds A3HoCl6 could be prepared also from acetic acid solutions. From aqueous solutions, the ternary halides Cs4HoCl7 and Cs3HoCl6 crystallizing in the space group Pbcm were prepared. Anhydrous HoCl3 can be obtained comfortably from holmium formiate at approximately 300 °C in an HCl gas stream.
Refractive indexes and electronic polarizabilities of molten HoCl3-NaCl and HoCl3-KCl mixtures
Shirao,Iida,Fukushima,Iwadate
, p. 163 - 168 (1998)
The refractive indexes of molten HoCl3-NaCl and HoCl3-KCl mixtures were measured by goniometry using visible light at eight wavelengths and expressed as functions of both temperature and wavelength into empirical formulas by a least-squares method. The electronic polarizabilities of ions in the mixture melts were obtained from the data of refractive indexes and molar volumes, and the polarizability of a Ho3+ ion was evaluated to be about 0.98 × 10-30 m3 according to the Clausius-Mossotti equation. The isotherms of these properties show little deviation from their additivity line.
