Abstract:
1. A compound oxide manufacturing method comprising: dispersing micelles, in each of which an aqueous phase is formed, in an oil phase; producing primary particles of a precursor of compound oxide including a metal ion in the aqueous phases in the micelles; synthesizing secondary particles by causing the primary particles to aggregate; generating electric repulsive force between the micelles by producing polarization in each of the micelles carried out by mixing a triethylammonium cation having an ionic radius larger than that of the metal ion into each of the micelles at least when the secondary particles are synthesized in the micelles; and causing the secondary particles to aggregate by breaking the dispersion state of the micelles, or by causing the micelles to coalesce.
