複合酸化物の製造方法
Document Type and Number:
Japanese Patent JP4812233
Kind Code:
B2
Abstract:
To provide a process for production of compound oxides having homogeneously diffused and mixed elements, there is provided a process for production of compound oxides, comprising contacting an organic phase having dissolved therein an organic compound which produces the hydroxide of a first element when hydrolyzed, with an aqueous phase containing a second element as an ion, to produce the hydroxide of the first element by hydrolysis reaction of the organic compound at the interface while incorporating the second element in the product, and firing the resulting product to produce a compound oxide of the first element and second element. Third or additional elements may be included in the aqueous phase to produce compound oxides comprising third or additional elements.
