This work presents the results of study of non-aqueous suspensions based on a solid state electrolyte Ce-0.8(Sm0.75Sr0.2Ba0.05)(0.2)O2-delta (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 15 nm formed a self-stabilizing suspension with a high value of zeta-potential (+ 31 mV) in the isopropanol/acetylacetone (50/50 vol.%) dispersing medium. The CSSBO thin films (2 mu m) that deposited on the dense electrode substrate of La2NiO4+delta (LNO) after sintering for 6 hat 1400 degrees C had a uniform microstructure with an average grain size of 4 mu m and total conductivity of 0.1 S/cm at 650 degrees C.
