AB  - A series of four different powders ceria doped Ce1-xErxO2-delta (0.05  lt = x  lt = 0.20) were synthesized by applying self-propagating reaction at room temperature (SPRT method). SPRT procedure is based on the self-propagating room temperature reaction between metal nitrates and sodium hydroxide, wherein the reaction is spontaneous and terminates extremely fast. The method is known to assure very precise stoichiometry of the final product in comparison with a tailored composition. XRPD, Raman spectroscopy, TEM and BET measurements were used to characterize the nanopowders at room temperature. It was shown that all obtained powders were single phase solid solutions with a fluorite-type crystal structure and all powder particles have nanometric size (about 3-4 nm). Densification was performed at 1550 degrees C, in an air atmosphere for 2 h. XRPD, SEM and complex impedance method measurements were carried out on sintered samples. Single phase form was evidenced for each sintered materials. The best value of conductivity at 700 degrees C amounted to 1.10 x 10(-2) Omega(-1) cm(-1) for Ce0.85Er0.O-3(2-delta) sample. Corresponding activation energies of conductivity amounted to 0.28 eV in the temperature range 500-700 degrees C.

AB  - Multiply doped ceria nanopowders were synthesized by applying MGNP (modified glycine/nitrate procedure). The overall concentration of dopants was kept constant (x = 0.2) whereby Gd ion as the main dopant was gradually substituted by Sm and by Sm + Y. The compositions of solid solutions were calculated by applying defect model introducing anion vacancy radius. Characterization of powders involved BET, TEM, XRD and chemical analyses. Densification was performed at 1500 degrees C, in an oxygen atmosphere for 1 h. The results showed that with increasing number of dopants, specific surface area of powders increased, followed by decrease of crystallite and grain sizes. Densification degree was also found to rise with increasing number of dopants. According to impedance measurements it was found that ionic conductivity was the highest 1.14 x 10(-3) S cm(-1) at 450 degrees C in sample doped with Gd, Sm and Y simultaneously.

AB  - Nanopowdered solid solution Ce(1-x)Fe(x)O(2-delta) samples (0  lt = x  lt = 0.1) were synthesized by a self-propagating room temperature synthesis (SPRT). XRD and Raman spectroscopy at room temperature were used to study the vibrational properties of these materials as well as the Fe solubility in ceria lattice. Results show that all obtained powders are solid solutions with a fluorite-type crystal structure and all powders were nanometric in size. The average size of Ce(1-x)Fe(x)O(2-delta) particles lies about 5 nm. The results of electrical properties of the sintered samples investigated by an ac impedance spectroscopy are also presented and discussed. It was confirmed that Fe(3+) doped ceria material has a potential as electrolyte for intermediate-temperature solid oxide fuel cell applications.

AB  - Nanometric powders of solid solutions of cerium oxide were obtained by a modified
glycine nitrate procedure. Solid solutions of the host compound CeO2 with one or more
dopants in the lattice were synthesized. Rare earth cations (Re = Yb, Gd and Sm) were added
to ceria in total concentration of x = 0.2 that was kept constant. The criterion in doping was
to keep the value of lattice parameter of ceria unchanged. The lattice parameters were
calculated by using the model that takes into account the existence of oxygen vacancies in the
structure.
