PROBLEM TO BE SOLVED: To provide a method and an apparatus for producing inorganic fine particles of a metal oxide or the like, having a high mass-productivity, being capable of controlling particle morphology such as particle diameter, particle shape, and the like, and providing fine particles which have excellent dispersibility without coagulation, uniformity of particles, and high crystallinity.SOLUTION: There is provided a method for producing inorganic fine particles by using a continuous hydrothermal reaction method. The method comprises: preparing a reaction precursor containing an aqueous solution or a slurry of an inorganic alkali salt by mixing a liquid in which an inorganic material is dissolved or suspended with an aqueous alkaline solution; uniformizing a concentration of the reaction precursor in a pressurized liquid phase; and thereafter carrying out the hydrothermal reaction. |
