In this study, oxide materials La1−xCaxScO3−α (x = 0.03, 0.05 and 0.10) were synthesized by the citric-nitrate combustion method. Single-phase solid solutions obtained in case of calcium content x 0.03 0.05, whereas a calcium-enriched impurity phase was found at 0.10. Water uptake release studied means thermogravimetric analysis, thermodesorption spectroscopy dilatometry. It shown that lower main leads to decrease water uptake. Conductivity measured four-probe direct current (DC) two-probe...
The paper presents the results of an investigation into thin single- and triple-layer ZrO2-Sc2O3-based electrolytes prepared using tape-casting technique in combination with promising electrodes based on La2NiO4+δ Ni-Ce0.8Sm0.2O2-δ materials. It is shown that pressing joint sintering single electrolyte layers allows multilayer structures to be obtained are free defects at layer interface. Electrical conductivity measurements a carried out longitudinal transverse directions both direct...
Dopant-induced local distortions in the crystal structure and electronic influence hydration of proton-conducting LaScO 3 -based perovskites.
Bain La1-xBaxScO3-δ impairs sintering and leads to a decrease in its ceramic density. Two approaches have been studied for obtaining dense ceramics: using high processing temperature the introduction of Co3O4 additive. An addition only 0.5 wt% additive, despite positive effect, causes noticeable violation stoichiometry, with partial decomposition material. This can lead formation cationic vacancies, which form associates oxygen vacancies significantly reduce ion proton conductivity...
The paper deals with synthesis and studies the materials high ionic conductivity on basis of which various electrochemical devices are created: gas sensors, electrolyzers, for dosed supply hydrogen water vapor, etc. Interest in study physicochemical properties oxide proton conductors is due to phenomenon transfer a solid body when not structural unit compound. LaScO 3 based considered promising because bulk at low temperature, chemical stability mechanical strength comparison well-known...
