Abstract
Official abstract text for this publication.
Perovskite materials of the general formula SrCeO 3 and BaCeO 3 are provided having improved conductivity while maintaining an original ratio of chemical constituents, by altering the microstructure of the material. A process of making Pervoskite materials is also provided in which wet chemical techniques are used to fabricate nanocrystalline ceramic materials which have improved grain size and allow lower temperature densification than is obtainable with conventional solid-state reaction processing.
First claim
Opening claim text (preview).
That which is claimed: 1. A process of making a nanocrystalline proton conducting ceramic having formula ACe x M 1 -xO 3 where A an Sr or Ba and M is selected from the group consisting of Y, Yb, Eu, Gd, Sm and X varies from 1 to 0 and having at least about a 3% weight loss of oxygen while maintaining the ratio of chemical constituents within the ceramic comprising the steps of: providing a stoichiometric ratio of precursor reactants in an aqueous solution; adding urea and a PVA…
