<p>Provided are methods with which satisfactorily shaped core-shell particles and hollow particles can be stably produced even in cases when reaction-solution concentration is high. A core-shell-particle production method is provided with a step in which, in a reaction solution including a dispersion medium, core particles, a metal-oxide precursor, and 0.01-0.25 mol of a complexing agent per 1 mol of metal in the precursor, the precursor is subjected to a hydrolysis and dehydration condensation reaction to form, on surfaces of the core particles, a coating layer comprising the metal oxide. A hollow-particle production method is provided with a step in which the obtained core-shell particles are heated to breakdown and remove the core particles.</p> |
