▎ 摘　　要

NOVELTY - The method involves using metallocene as a magnetic agent, uniformly mixing with carbon material needed to be processed, under an atmosphere of oxygen content of 0-22%, mixing uniformly, placing into a quartz tank, sealing, canning the sealed quartz into an electric furnace, not needing to protect atmosphere, using electric furnace to heat, naturally cooling to room temperature, opening the closed quartz tank and collecting carbon-coated magnetic nanoparticles of the magnetic carbon material on the surface of the carbon material. USE - Magnetization method of magnetic carbon material used in military application. Can also be used in wave-absorbing stealth, and electromagnetic radiation pollution. ADVANTAGE - The method is simple and efficient method for magnetizing the carbon material, the magnetized function structure is stable, the magnetic performance intensity is adjustable, it is very suitable for mass production, and the magnetic nano-particles outside of the carbon coating, can be used as protective layer, preventing the outside air, carbon dioxide and water or acid and alkali material erosion magnetic nano particles, metal nano particles than those exposed outside. The metal oxide nano particles are stable, and even in the acidic solution, they are stable.
