Addition of (A) blocking agent(s) in a ceramic membrane for blocking crystalline growth of grains during atmospheric sintering |
摘要 |
A method of preparing a composite includes the following steps. A powder blend is sintering while an oxygen partial pressure (pO2) of a gaseous atmosphere surrounding the powder blend is controlled. Before the sintering, a shape is formed from the powder blend. After the forming and before the sintering, binder is removed from the powder blend. The powder blend comprises binder, a mixed electronic/oxygen O2− anionic conducting compound (C1) and a compound (C2) chosen from MgO and BaTiO3. The resultant composite comprises at least 75 vol % of compound (C1), from 0.01 to 25 vol % of compound (C2), and from 0 vol % to 2.5 vol % of compound (C3). |
