Abstract
A method of preparing a composite includes the following steps. A powder blend is sintering while an oxygen partial pressure (pO) 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 Oanionic conducting compound (C) and a compound (C) chosen from MgO and BaTiO. The resultant composite comprises at least 75 vol % of compound (C), from 0.01 to 25 vol % of compound (C), and from 0 vol % to 2.5 vol % of compound (C).
