An examination was made of the influence of the concentration of an oxidative solution of potassium bichromate in sulphuric acid on processes of thermo-oxidative breakdown and the coefficient of swelling of intercalated graphites. It was established that the resistance of intercalated graphites to thermal oxidation depends not only on the concentration of the oxidative solution used for intercalation but also on the graphite/potassium bichromate/sulphuric acid ratio.
