NOVELTY - Nanographite sheet structure comprising graphene layers, is claimed. The nanographite sheet structure has: bulk density (tap density) of 0.01-0.1 g/cm3; thickness of 1-10 nm; plane transverse size of 1-10 um; and specific value of plane transverse size and thickness of 10-10000. The sheet is stacked with 30-300 of graphene layers. USE - The nanographite sheet structure is useful for processing natural graphite.
