Abstract
This manufacturing process has: a step of performing a heating treatment in a contact state of SiC with Clto form a porous carbon material; a step of reacting SiClformed 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 ZnClformed by reaction of SiClwith Zn, to extract Zn and Cl. 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, Clextracted by reduction of ZnClis used in the step of forming the porous carbon, and Zn extracted by reduction of ZnClis used in the reaction step of SiClwith Zn.
