| 简介 |
A method of manufacturing an ionic conductor to improve oxygen Ion conductivity that is otherwise reduced by the presence of deleterious impurities comprising silicon or silicon containing compounds. In accordance with the Invention a dissolved salt of a dopant consisting of an alkaline-earth metal is applied to an oxygen Ion conducting material composed of doped ceria, doped zirconia, or doped lanthanum gallate and having the impurities. The solution can also be applied with equal success to cation salts and oxides used in making the oxygen Ion conducting material. The oxygen Ion conducting material with the solution applied thereto is thoroughly mixed and then heated to evaporate the solvent and to decompose the alkaline-earth salt and thereby to form said ionic conductor. |
