ABSTRACT:
For the production of sintered lanthanum manganite bodies, such as tubes for solid oxide fuel cell air electrodes, there is used extrudable lanthanum manganite paste having a pH of not less than 8, of a dried unfired extruded lanthanum manganite body formed of material having a pH, measured by grinding the material and diluting with water, of at least 7.3. Providing alkalinity in such a paste or body reduces crack formation and increases productivity.
