Abstract

The results of X-ray studies of samples of purified and thermally modified shungite carbon are presented. The quantitative characteristics of short-range order are determined, and 3D models of regions of short-range ordering are presented. It is found that the structure of these regions can be described by turbostratic models, which are sets of five distorted graphene sheets, disoriented relative to each other, with sizes of 26 × 27 Å. The cluster thickness is 15 Å. The average distance between the sheets is 3.5 Å. As a result of the heat treatment of shungite carbon samples, graphene sheets are exfoliated. The thickness of the clusters forming the structure of regions of short-range ordering decreases to 7 Å.
