Abstract:
1. A method selected from: a) a method of densifying a lanthanide chromite ceramic, said method comprising: mixing the lanthanide chromite ceramic with sintering aids, the sintering aids comprising one or more spinel oxides; and sintering the mixture at a sintering temperature from about 1100° C. to about 1500° C.; b) a method of densifying a multi-phase conducting ceramic mixture containing a lanthanide chromite ceramic and one or more ionically conducting ceramics said method comprising: mixing the lanthanide chromite ceramic, the one or more ionically conducting ceramics, and sintering aids, the sintering aids comprising one or more spinel oxides, and sintering the mixture at a sintering temperature from about 1100° C. to about 1500° C.; and c) a method of densifying a multi-phase conducting ceramic mixture comprising a lanthanide chromite ceramic and one or more ionically conducting ceramics, said method comprising: mixing the lanthanide chromite ceramic and the one or more ionically conducting ceramic with sintering aids, the sintering aids comprising one or more spinel oxides, and sintering the mixture at a sintering temperature from about 1100° C. to about 1500° C. in an air atmosphere, wherein the one or more spinel oxides are selected from the group consisting ZnMn
