An object of the present invention is to suppress an increase in particle size due to aggregation in a metal oxide fine particle dispersion, and stably disperse metal oxide particles to a small size on the order of several nm. SOLUTION: A mixture suspension of cobalt hydroxide and aluminum hydroxide is supplied together with hot water at 390 ° C., particle formation reaction is performed in the flow reactor 14, and the reaction solution is discharged from the flow reactor 14. In the middle of the process, the dispersant is continuously supplied. [Selection] Figure 1 |
