摘　　要：石墨是制备高温气冷堆球形燃料元件的主要和关键原材料。高温气冷堆球形燃料元件用核级石墨粉包括天然石墨粉和人造石墨粉。微观结构深刻影响粉体的物化性能,物化性能则进一步影响基体石墨粉和球形燃料元件的加工工艺,本文详细介绍了高温气冷堆球形燃料元件用核级天然石墨粉和人造石墨粉的特性、微观结构及制备工艺。The graphite is the main and key raw material for the preparation of spherical fuel element in high temperature gas cooled reactor. Nuclear grade graphite powder for spherical fuel element in high temperature gas cooled reactor includes natural graphite powder and artificial graphite powder. The microstructure profoundly affects the physicochemical properties of powder, which further affects the processing technology of matrix graphite powder and spherical fuel element. In this paper, the characteristics, microstructure and preparation technology of nuclear grade natural graphite powder and artificial graphite powder for spherical fuel element of high temperature gas cooled reactor are introduced in detail.
