Trivalent lanthanides (La, Eu and Tm) hydroxides and oxides aged at from 25°C to 90°C in the neutral to alkaline pH_c condition were investigated by X-ray diffraction (XRD), small angle X-ray scattering (SAXS) and X-ray absorption fine structure (XAFS) techniques. The structure of solid phases were discussed to explain their solubilites.
