<p>This manufacturing process has: a step of performing a heating treatment in a contact state of SiC with Cl2 to form a porous carbon material; a step of reacting SiCl4 formed along with the porous carbon material in the foregoing step, with Zn to extract Si; and a step of reacting Si extracted in the foregoing step, with C to form SiC, and the process further has: a step of reducing ZnCl2 formed by reaction of SiCl4 with Zn, to extract Zn and Cl2. These steps are repetitively carried out, SiC extracted by the step of forming SiC is used in the step of forming the porous carbon material, Cl2 extracted by reduction of ZnCl2 is used in the step of forming the porous carbon, and Zn extracted by reduction of ZnCl2 is used in the reaction step of SiCl4 with Zn.</p> |
