The invention discloses a synthesis method of a carbon material with super-high hardness, and belongs to the technical field of preparation of super-hard materials. The preparation method comprises the following specific steps: dispersing fullerene into nano diamond powder, uniformly mixing, putting into a high-pressure device, sintering for 1 hour under the conditions of temperature and pressureof 13GPa and 2100k, quenching a sample, relieving the pressure to normal pressure, grinding, polishing and cleaning to obtain the pure composite super-hard carbon material. According to the invention,the composite super-hard carbon material is prepared by doping with a small amount of fullerene and sintering at high temperature and high pressure, and the prepared composite superhard carbon material has great application potential and value in the fields of aerospace, geological exploration, machine tools and the like. 本发明的一种具有超强硬度的碳材料的合成方法属于超硬材料制备的技术领域。具体步骤为：将富勒烯分散于纳米金刚石粉末中，混合均匀后放入高压装置中，13GPa，2100k的温压条件进行烧结1小时，样品淬火、卸压
