A series of carbon-mineral composites with the carbon content varying from 1.5 to 12.2 wt.% was synthesized by MgO carbonization in 1,3-butadiene at 600 oC. The synthesized carbon-mineral composites were studied by EPR, XRD and transmission electron microscopy. It was shown by EPR that the MgO surface was completely covered with carbon after depositing 8-10 wt.% C. MgO from the composite was dissolved by treatment in hydrochloric acid. The surface area of the carbon samples obtained after the acid treatment was studied by thermal desorption of argon. It was shown that the synthesized carbon material consisted of several graphene layers. Specific surface area of the synthesized graphene had a maximum about 1800-1900 m2/g for samples obtained from C-MgO composites containing 8-10 wt.% C.
