ABSTRACT:
A process for producing hollow structures of carbon material having desired shape and properties of carbon by obtaining a carbon paste composition, molding portions of the hollow structure by a method selected from the group consisting of an injection molding method, an extrusion molding method, a casting method or a fluidizing method, bonding the molded portions together using a paste composition, solidifying the bonded portion by precarbonizing, the hollow structures thus provided, and then calcining in an inert gas atmosphere as required. Hollow structures of carbon materials having a rigid bond, excellent impermeability, and complicated shape can be readily accurately and inexpensively produced without working after calcining.
