    Abstract: PURPOSE: To obtain hard carbon optimum for a part material required of high hardness, e.g., cutting tools, digging tools or a sliding part material, further having electroconductivity. CONSTITUTION: This hard carbon is a mixture of an amorphous carbon and a diamond-resembled structure having >=2000kgf/mm Vickers hardness and 1×10 -1×10 Ω.cm electric resistance (at room temperature). This material is obtained by using a carbon cluster such as fullerenes as a raw material and using Al flux, as necessary, and using a belt cylinder-type high pressure machine or a piston cylinder-type high pressure machine at >=2.0GPa pressure and at 600-900 deg.C.
