AB  - This paper deals with a new method for producing non-oxide ceramic using wood as a template. Highly porous silicon carbide (SiC) ceramic with woodlike microstructure has been prepared by carbothermal reduction reactions of Tilia wood/TEOS composite at 1873K. Wood specimens were carbonized at 1273K in Ar atmosphere for 2 hour. The porous carbon preform was infiltrated with TEOS (Si(OC(2)H(5))(4)), as a source of silica, without pressure at 298K. The infiltration/annealing processs was repeated up to five times to increase the SiO(2) content in the bionnorphic samples. The morphology of resulting porous SiC ceramics, as well as the conversion mechanism of wood to porous SiC ceramics, have been investigated by mean of scanning electron microscopy (SEM/EDS) and X-ray diffraction analysis (XRD). Experimental results show that the biomorphic cellular structure of wood is preserved after thermal treatment as a porous SiC ceramics. Obtained SiC ceramics consists of beta-SiC with traces of alpha-SiC.

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  - This paper deals with Nd-doped ceria solid solutions: Ce(1-x)Nd(x)O(2-delta) with x ranging from 0 to 0.25. Six different powders were synthesized by applying the method based on self-propagating room temperature reaction (SPRT) between metallic nitrates and sodium hydroxide. The method is known to assure very precise stoichiometry of the final product in comparison with a tailored composition. Rietveld refinement was employed to get structural information on the. synthesized powder. An increase of Nd ion concentration increases the unit cell parameters and average bond distances. We have shown that all obtained powders were solid solutions with a fluorite-type crystal structure and all powder particles were of nanometric size (about 3 nm).

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 Sin) 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.
