(JP9309768-A)      A composite ceramic powder is composed of composite particles, each comprising primary particle clusters existing unevenly on surface of secondary particle clusters.    Also claimed is a production method for the above composite ceramic powder.    Pref. the composite particles are spherical; the primary particles comprise yttria-stabilised zirconia and the secondary particles comprise NiO; and in the mist, the primary particle raw material is solidified, and the secondary particle raw material is in solution, or both the primary and secondary particle raw materials are in solution and the concentration of the primary particle raw material is higher than that of the secondary particle raw material.    USE -   For solid electrolytic fuel cell electrodes (claimed), solid electrolytic fuel cells (claimed), and as a material for other ceramic products, such as catalyst materials.    ADVANTAGE -   The fuel electrode has high performance, excellent long-term stability, and a smaller polarisation value than fuel electrodes made from powders prepared by normal mixing methods or drip pyrolysis.
