ABSTRACT:
Ultradispersed ones of primary particles of nanometer-sized carbon are obtained by applying a wet-type milling method and/or a wet dispersion method to an aggregate structure of the primary particles to overcome van der Waals forces, by which forces the primary particles are held together to form the aggregate structure, whereby the ultradispersed primary particles are obtained in a colloidal dispersion on a large-scale basis at low cost without using any additive. In a method of manufacturing the ultradispersed primary particles, the wet-type milling method is carried out in a ball mill, preferably in combination with a high-energy ultrasonic-wave process carried out in a dispersing medium such as pure water, whereby a colloidal solution or slurry with a low-concentration of the primary particles ultradispersed in the dispersing medium is obtained.
