The invention discloses a method for preparing a nano-graphite coating on the surface of a graphite product and belongs to the field of new materials. The coating is suitable for the surfaces of all graphite carbon material products. The coating is prepared through surface microstructure adjustment, surface oxidation and high-temperature sintering. The nano-graphite coating is suitable for protecting volatile carbon materials, inhibiting the powder falling phenomenon at normal temperature and inhibiting the volatilization of the materials at high temperature. The carbon material coated with the coating is especially suitable for growth protection of high-purity single crystal materials. 本发明公开了一种石墨制品表面制备纳米石墨涂层的方法，属于新材料领域，该涂层适用于所有石墨类碳材料制品表面。该涂层通过表面微结构调整、表面氧化、以及高温烧结得到。适用于保护可挥发性碳材料，常温下抑制掉粉现象，高温下抑制材料挥发。该覆有涂层的碳材料尤其适用于高纯单晶材料的生长保护。
