Optimization of microstructure and properties of acceptor-doped barium cerate

The presented research concerns acceptor doped barium cerate and the attempts of improvement of its production method that would allow obtaining the solid electrolyte characterized by the particular properties. The authors suggest combining two production methods, molten salt synthesis and self-combustion, in order to achieve the compound material that has some of the advantages of both of the initial methods. An impact of nickel addition on the phase purity, morphology, density and conductivity of the sample was also studied. The results of the investigation appeared to be very promising, as the resulting sample meets the requirements typical for proton conductors.
