COMPOSITE CERAMIC POWDER AND METHOD FOR PRODUCING THE SAME, AND SOLID OXIDE FUEL CELL |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a composite ceramic powder which is excellent in distribution properties at nanometer level of oxide particles and composition controllability. <P>SOLUTION: The composite ceramic powder includes at least a perovskite type oxide represented by A<SB>1-x</SB>B<SB>x</SB>C<SB>1-y</SB>D<SB>y</SB>O<SB>3</SB>or nickel oxide and zirconia in which a metal ion is dissolved as a solid solution and the oxygen ion conductivity is given, and is made first by forming a basic zirconium carbonate complex by reacting zirconium ion and carbonate ion in a basic aqueous solution, and then coprecipitating one or more kinds of metal ions selected from the group consisting of A, B, C and D which compose A<SB>1-x</SB>B<SB>x</SB>C<SB>1-y</SB>D<SB>y</SB>O<SB>3</SB>or nickel ion and metal ions along with the basic zirconium carbonate complex, and heat-treating the precipitate at a temperature of 200°C or higher. <P>COPYRIGHT: (C)2011,JPO&INPIT |
