▎ 摘　　要

NOVELTY - A carbon material comprises a calcined product of a compound including three or more phenolic hydroxyl groups in the molecule. USE - Carbon material used in composition for improving lubricant agent (all claimed). Can also be used as carbon nanotubes, fullerene, graphite, graphene, graphene oxide, reduced graphene oxide, artificial graphite and carbon black. ADVANTAGE - The carbon material is capable of avoiding contamination of impurity metals derived from a catalyst, which occurs when manufactured by utilizing a catalytic reaction on a nickel substrate, and provides lubricity improver having excellent lubricity. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a carbon material composition, which comprises the carbon material; (2) a lubricity improving agent, which comprises the carbon material; and (3) manufacture of the carbon material, which involves calcining the compound including three or more phenolic hydroxyl groups in the molecule at 200-2000 degrees C.
