AB  - Ultrafine Ce1-xNdxO2-delta (x = 0-0.25) powders were synthesized by self-propagating room temperature synthesis. Raman spectra were measured at room temperature in the 300-700 cm(-1) spectral range. The shift and asymmetric broadening of the Raman F-2g mode at about 454 cm(-1) in pure and doped ceria samples could be explained with combined size and inhomogenous strain effects. Increased concentration of O2- vacancies with doping is followed by an appearance of new Raman feature at about 545 cm(-1). (c) 2005 Elsevier Ltd. All rights reserved.

AB  - The thermodynamic assessment of the ternary Cu-Pb-O system was carried out by the CALPHAD method. The thermodynamic properties of the phases are described using a compound energy formalism (CEF) for the various solid phases and an ionic two-sublattice model for the liquid. The thermodynamic parameters of the sub-systems Cu-O, Pb-O and Cu-Pb are adopted from recent assessments. Ternary interaction parameters of the liquid phase have been optimized on the base of the selected literature data (phase diagram and activity of oxygen). The ternary system shows a large liquid miscibility gap of peculiar shape, which connects to the miscibility gaps in each of the binary sub-systems. Calculated phase diagrams are compared with the experimental data.

AB  - Silicon nitride-based compositions containing zirconia and ceria additives were prepared by hot pressing in argon atmosphere. The compositions studied can be divided into two groups: (a) with a constant total amount of ZrO2 + CeO2 additive (32 mol.%) within which the CeO2 content was varied from 0 to 6.2 mol.%, and (b) with various contents (10 to 42 mol.%) of ZrO2 + CeO2 additive, the ratio of ZrO2 to CeO2 staying constant at a level of 7.35 : 1. Phase compositions were determined by X-ray powder diffraction (XRD), while energy-dispersive X-ray microanalysis (EDX) was used for compositional analysis of the ZrO2 grains. The results showed that after sintering the Ce4+ ions were reduced to Ce3+. At low initial ceria concentrations, Si2N2O was formed beside beta -Si3N4 and ZrO2 (the majority of which was monoclinic). At higher ceria concentrations, however, Si2N2O disappeared by reaction with ceria and silica to form Ce-N apatite. Nitrogen-containing zirconia phases were not found in the studied compositions, up to 1750 degreesC.
