The ceria solid solutions doped with rare earth cations were synthesized by two methods and the microstructural and morphological characterization of powders was performed. The results obtained by X-ray diffraction (XRD), transmission electron microscopy (TEM), Brunauer-Emmett-Teller (BET) method and Raman spectroscopy were studied and discussed. The results showed that finer powders have not only higher specific surface area, smaller particles and crystallite sizes, but also larger lattice parameters in the case of both single and multidoped solid solutions.
