Electrophoretic deposition of a self-stabilizing suspension based on a nanosized multi-component electrolyte powder prepared by the laser evaporation method

This work presents the results of study of non-aqueous suspensions based on a solid state electrolyte Се0.8(Sm0.75Sr0.2Ba0.05)0.2O2-δ (CSSBO) prepared by the method of high-energy material dispersion–laser evaporation of the ceramic target. The thermal behavior of the powder was studied by thermogravimetric and differential thermal analysis (TG-DTA); the sintering kinetic was investigated by the dilatometric method. Electrokinetic study showed that the powders with nanoparticles that had an average diameter of 15nm formed a self-stabilizing suspension with a high value of ζ-potential (+31mV) in the isopropanol/acetylacetone (50/50vol.%) dispersing medium. The CSSBO thin films (2μm) that deposited on the dense electrode substrate of La2NiO4+δ (LNO) after sintering for 6h at 1400°C had a uniform microstructure with an average grain size of 4μm and total conductivity of 0.1S/cm at 650°C. •Се0.8(Sm0.75Sr0.2Ba0.05)0.2O2-δ (CSSBO) was obtained by laser evaporation method.•Self-stabilizing CSSBO suspension with a high ζ-potential value was prepared.•Cathode support of 84% relative density was made of La2NiO4+δ.•EPD method was applied to obtain CSSBO thin films (about 2μm).•Total conductivity for the deposited CSSBO film was equal to 0.1S/cm at 650°C.
