Abstract
A modification of a solution method for preparing solid oxide electrolyte films was developed. It is based on using a suspension consisting of a solution of inorganic salts and of a nanodispersed precursor powder prepared from the same solution. As demonstrated by the example of calcium zirconate, this procedure allows the number of applications of the liquid-phase precursor, required to obtain a dense electrolyte film on a porous support, to be considerably decreased relative to the procedure using a salt solution. The influence of the concentration of the precursor powder in the suspension on the microstructure of CaZr0.9Y0.1O3–δ films was analyzed.
