Abstract

Provided is a more suitable method for producing ceramic microparticles. The present invention uses at least two types of fluids to be processed; at least one of the fluids to be processed is a fluid containing a ceramic starting material liquid that mixes and/or dissolves a ceramic starting material in a basic solvent; of the fluids aside from the ceramic starting material liquid, at least one of the fluids to be processed is a fluid containing a solvent for precipitating ceramic microparticles; and ceramic microparticles are precipitated by mixing the fluid containing the ceramic starting material liquid and the fluid containing the solvent for precipitating ceramic microparticles within a thin film fluid formed between at least two surfaces () for processing that are provided facing each other, are able to approach and separate each other, and of which one is able to rotate with respect to the other. Ceramic microparticles having as increased crystallinity are obtained by mixing the fluid containing the precipitated ceramic microparticles precipitate and a fluid containing an acidic substance.
