ABSTRACT:
A compound oxide manufacturing method includes: dispersing micelles, in each of which an aqueous phase is formed, in an oil phase; producing primary particles of a precursor of compound oxide in the aqueous phases in the micelles; synthesizing secondary particles by causing the primary particles to aggregate; and causing the secondary particles to aggregate by breaking the dispersion state of the micelles, or by causing the micelles to coalesce. In particular, polarization is produced in each of the micelles with the use of a cation having an ionic radius larger than that of a metal ion at least when the secondary particles are synthesized in the micelles.
