Abstract
This invention relates to a method for preparing fine graphite particles which can be used as a highly functional graphite material in wide applications. According to this method, foliated fine graphite particles having a high aspect ratio and hence well-developed anisotropy can be prepared, without formation of secondary particles, by dispersing expanded graphite particles into a liquid and then exposing them to ultrasonic waves. Articles molded of the resulting foliated fine graphite particles exhibit high electrical conductivity and thermal conductivity.
