Document Type and Number:
WIPO Patent Application WO/2019/146411
Kind Code:
A1
Abstract:
Provided are: a fine particle production method that makes it possible to control the acidity, i.e., a surface property, of fine particles; and fine particles. A fine particle production method in which a raw material powder is used to produce fine particles by means of a gas phase method. The fine particle production method has a step for supplying an organic acid to raw material fine particles. The gas phase method is, for example, a thermal plasma method or a flame method. The fine particles have a surface coating that includes at least a carboxyl group.
