NOVELTY - The manufacturing method involves preparing intercalated graphite by treatment of crystalline graphite with a solution of ammonium persulfate in sulfuric acid. The resulting intercalated graphite compound is subjected to aging process prior to expansion. The graphite compound is added with glycerin and subjected to carbamide treatment. The dispersion of graphite is carried out by passing through a gap between a body and a rotary disk under a pressure of 0.2-2 megapascals. The gap between the surfaces of the body and the rotary disk is 0.2 mm or less. USE - Manufacturing method for graphene-containing materials. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a device for producing graphene-containing materials.
