Figure 5. (A) Schematic scheme of the hot spot formation at the contact point between two carbon particles leading to the formation of a continuous graphitic structure between the two particles; (B) Digital photo of the carbon block formed within the reactor after CMD process under IH mode; (C) Cross-section of a TomoX micrograph showing the connection between different MESOC+-1 extrudates through a graphitic-like carbon layer (in bright color); (D) Simulation of the magnetic field concentration in the middle of the induction coil; (E) Digital and (F) thermal photos of the reactor under reaction where a bright zone can be observed in the middle of the induction coil; (G) Digital photo showing the high mechanical resistance of the C-C composite generated during the CMD process with a wt/wt ratio of ca. 2,800 times. CMD: Catalytic decomposition of methane; IH: induction heating.
