摘要：NOVELTY - An additive comprises rare earth compound or rare earth metal powder, with rare earth compound comprising rare earth oxide, rare earth carbide and/or rare earth halide. USE - Additive used for generating low resistance and high-density graphite material (claimed). ADVANTAGE - The additives utilizes rare earth compound restraining physiosis generated by nitrogen and sulfur in graphitizing process, and similar homogeneous phase catalytic graphitization to graphitizing process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a production of high-thermal conductivity, low-resistance and high-density graphite material comprising ball milling and screening by sieve of 200 meshes, mixing with coke and carbon fiber, adding asphalt adhesive, kneading and molding, roasting and soaking-roasting twice, and graphitizing to produce into graphite material.
