The effect of the Ln3+ cation type on composition and structure a wide range hydrated lanthanide chromates (Ln = La, Pr, Nd, Sm, Eu, Gd, Dy, Ho, Yb, Y) has been studied. It was found that Ln can be divided into several groups in terms their structure. synthesized light lanthanides crystallize heptahydrates [Ln2(CrO4)3(H2O)s] 2H2O Sm) tetrahydrate Eu2(CrO4)3.4H2O with monoclinic (sp. gr. P21/c). heavy remain X-ray amorphous.
The effect of synthesis conditions on the features long- and short-range order Ln2(WO4)3 (Ln = Gd, Dy, Ho, Yb) powders synthesized via coprecipitation salts has been studied by a complex physico-chemical techniques including synchrotron X-ray powder diffraction, absorption spectroscopy, Raman infrared simultaneous thermal analysis. It was found that crystallization amorphous precursors begins at 600 °C/3 h leads to formation monoclinic structure with sp. gr. C12/c1(15) for Dy) P121/a1(14) Ln...
