核能对环境污染小，能源材料需求量低，是解决我国能源问题的有效手段, 用于核反应堆的炭石墨材料称为核反应堆石墨，简称核石墨。

高纯石墨是核反应堆用优异中子减速材料，是多晶材料，石墨化度高，要求纯度高，以防止热中子吸附在慢化块上，并具有各向同性使其在高中子辐射条件下，在三维空间上具有稳定性。

GNuclear energy has little environmental pollution, Low demand for energy materials, is an effective means to solve China's energy problems, carbon graphitematerials used in nuclear reactors are called nuclear reactor graphite, referred to as nuclear graphite.

High-purity graphite is an excellent neutron deceleration material for nuclear reactors, is a polycrystalline material, has a high degree of graphitization, requireshigh purity, to prevent thermal neutrons from adsorbed on the moderating block, and has isotropy to make it stable in three-dimensional space under thecondition of high-neutron radiation.
