description: The subject of the graduate qualification work is Â«Liquid-phase synthesis and physic-chemical properties of nanopowders and ceramic electrolyte materials in the CÐµO2-Nd2O3Â systemÂ». This work is devoted to the liquid-phase synthesis of nanopowders and ceramic, electrolyte materials in the CÐµO2-Nd2O3Â system based on them for medium-temperature fuel cells by methods of joint deposition of metal hydroxides and joint crystallization of salts. Tasks that were solved during the study: liquid-phase synthesis of precursor nanoparticles by methods of co-deposition of hydroxides and co-crystallization of salts of the compositions: (CeO+)0.95(Nd2O3)0.05, (CeO2)0.90(Nd2O3)0.10, (CeO2)0.85(Nd2O3)0.15,Â  (CeO2)0.80(Nd2O3)0.20, (CeO2)0.75(Nd2O3)0.25; study of the process of consolidation of ceramics: selection of modes of pressing and sintering of samples;selection of sintering additives and study of their effect on the density and porous structure of the resulting ceramics;study of the influence of the concentration composition of ceramics and the conditions of liquid-phase synthesis on the physic-chemical properties of the obtained ceramic materials;conducting a comprehensive study of the physicochemical properties of synthesized nanopowders and ceramic electrolyte materials. In the course of the work, the thermolysis process in synthesized precursor powders Â was studied by differential thermal analysis (DTA), the microstructure of the obtained powders was studied by low-temperature nitrogen adsorption (BET), the phase composition of the obtained ceramics was studied by X-ray phase analysis (XFA), the open porosity and apparent density of samples was studied by hydrostatic weighing, the electrophysical properties of the obtained ceramic materials were studied by two-contact the method of measuring electrical conductivity and the West-Tallan method. As a result of a comparative analysis, it was revealed that the best characteristics are a sample of the composition (Ð¡eO2)0,85(Nd2O3)0,15Â with a sintering additive of 3 wt. % ZnO. It is shown that ceramic nanomaterials in the CÐµO2-Nd2O3Â system are promising as solid oxide electrolytes of medium-temperature fuel cells by their mechanical (open porosity, density) and electrophysical (magnitude, type and mechanism of electrical conductivity) properties.
