Method of manufacturing a carbon material and the carbon material

摘要

A method of manufacturing a surface-modified carbon material is provided that can form a layer of a metal or the like on the surface in a simple manner and with adhesion performance. The surface-modified carbon material is also provided. The method is characterized by heat-treating a carbon substrate together with a carbon member other than the carbon substrate, the carbon substrate embedded in a surface modifying agent comprising a pyrolytic hydrogen halide generating agent and metal particles containing a transition metal. More specifically, a carbon substrate (2) is embedded in powder (3) containing a pyrolytic hydrogen halide generating agent such as ammonium chloride and metal particles containing a transition metal such as stainless steel, and the carbon substrate (2) is heat-treated together with a carbon member other than the carbon substrate, such as a the graphite crucible (6).
