Abstract—The structure of natural crystalline and cryptocrystalline graphites from deposits of Krasnoyarsk krai is investigated by means of XXray structural analysis using a D8 Advance diffractometer (Bruker, Germany). The variations in types and parameters of the crystal lattice due to the mechanical activation or mechanical synthesis of the material are revealed and the optimal activation modes of graphite at which they occur are established. The influence of the treatment time on the structural parameters of both types of graphites is considered. It is shown that their physicochemical properties are improved at the optimal activation duration due to the variation in the type and lattice parameters as well as amorphization of the crystal structure.
