Abstract
A process for producing fine particles with a high aspect ratio and/or a low specific surface area includes use of a jet mill. An alkaline grinding aid is added to a grinding gas before the grinding gas is fed into a grinding chamber of the jet mill. The process includes micronization of particles of layered structure material having an interplanar distance ranging from 0.30 nm to 0.40 nm as measured by X-ray diffraction method.
