AB  - Nanometric size ceria powder particles were obtained by applying modified glycine/nitrate, as well as self propagating room temperature methods. The powders were doped and co-doped with rare earth cations in the concentration range 0 :5 x :! 0.25. The results showed that by doping with one or more dopants simultaneously in the mentioned concentration range solid solutions with host ceria were formed. Differences in the properties of nanopowders obtained by the two methods were discussed. Defect model introducing anion vacancy radius was applied to calculate lattice parameters of single doped and co-doped ceria nanosized solid solutions.

AB  - A nano-sized CeO2 powder was synthesized by a modified glycine nitrate process (MGNP). The synthesized powder was characterized by X-ray diffraction (XRD), the Brunauer Emmett Teller (BET) method, and transmission electron microscopy (TEM). The lattice parameter and crystallite size were determined by the Rietveld refinement of X-ray diffraction patterns. The shrinkage kinetics of the green body was continuously monitored in air and in oxygen atmospheres using a high temperature dilatometer up to 1500 degrees C. During the high temperature sintering in redox reaction occurred (Ce4+ was partially reduced to Ce3+ and oxygen gas was released). The redox reaction influenced the sintering behaviour of CeO2, resulting in a decrease in density. On the basis of shrinkage kinetics data in oxygen atmosphere a master sintering curve for CeO2 was constructed. Using the concept of the master sintering curve, the densification behaviour in oxygen atmosphere was successfully predicted from early to final stages of sintering. During sintering of CeO2 at lower temperature in air atmosphere a significant contribution of the surface diffusion was observed.

AB  - Nanopowdered solid solution Ce1-xY(Nd)(x)O2-delta samples ( 0.1 LT = x LT = 0.25) were made by self-propagating room temperature (SPRT) synthesis. The first-order Raman spectra of Ce1-xY(Nd)(x)O2-delta samples measured at room temperature exhibit three broad features: the main Raman active F-2g mode at about 450 cm(-1) and two broad features at about 550 (545) and 600 cm-1. The mode at similar to 600 cm(-1) was assigned to the intrinsic oxygen vacancies due to the nonstoichiometry of ceria nanopowders. The mode at about 550 (545) cm(-1) was attributed to the oxygen vacancies introduced into the ceria lattice whenever Ce4+ ions are replaced with trivalent cations (Y3+, Nd3+). The intensity of this mode increases with doping in both series of samples, indicating a change of O2- vacancy concentration. The mode frequency shifts in opposite direction in Y- and Nd-doped samples with doping level, suggesting that different types of defect space can occur in Y- and Nd-doped ceria nanopowders.

AB  - One of the methods for powder synthesis that is both cost and time effective is the self-propagating room temperature synthesis. We applied this method to synthesize rare earth doped ceria nanopowders. Since they exhibit very high ionic conductivity at intermediate temperatures these compositions are attractive for a new generation of nanostructured ceramics applicable in solid oxide fuel cells as electrolytes. In this paper we paid our attention to the reaction based on methathetical pathway, whereby solid solution nanopowders of rare earth elements with ceria were obtained at room temperature. Compositions of Ce1-xRexO2-delta (Re = Y, Nd) were synthesized with x ranging from 0 to 0.20. The reaction course is discussed and the properties of the obtained powders are presented.
