Molding material for producing carbon clusters and a method for manufacturing thereof

A method for producing a molding material for producing carbon clusters, comprising the following steps:

• obtaining a molded precursor containing a calcined biomass and a binder, the calcined biomass being a biomass from a renewable source;
• optionally, further baking the molded precursor;
• and
• graphitizing the molded precursor at a temperature of 2500° C. or higher, thereby obtaining the molding material,
• wherein biomass-derived material in the precursor is 50 mass % or more,
• wherein the method further comprises adding and adjusting the moisture content of a precursor before graphitization of the molding material to be greater than 3.2 mass % and less than 12.6 mass % of the total precursor,
• wherein the molding material is graphitized,
• wherein the molding material has an electrical resistivity that is equal to or less than 100 μΩm, and
• wherein the molding material has a diffraction pattern by a powder X-ray diffraction method with one peak between 2θ (θ is the Bragg angle) of 26 to 27°, and a value of ⅓ width divided by a base of the peak is equal to or less than 0.68.
