Zusammenfassung:The process comprises high-energy oxidation of graphite in a mixture of oxygenated inorganic acids under the action of potassium nitrate and oxygenated water. The graphite particle size is also increased by "hot-cold" heat treatment. The product can be used to prepare aqueous or organic suspensions of colloidal graphite, without the need for prolonged grinding.
