Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a simple method for increasing an average particle size and a pore volume, especially bringing the fine particles to be flat and a method for modifying a fine particle dispersion to enhance quality of products made by using the fine particles. SOLUTION: The method for improving a fine particle dispersion is to treat a fine particle dispersion having ≤1 μm average particle size D0by dynamic light scattering to aggregate by using a wet medium mill and bring the average particle size D to be D>2D0. In the method for improving the fine particle dispersion, the wet medium mill is a wet medium-stirring mill, and furthermore, a pulverization medium is beads having a 5 g/cm3true density.
