采用γ-射线辐照法，在常温常压下从水溶液中制备了由纯六方相和六方相与少量立方相混合组成的纳米晶钴粉。详细研究了实验条件对纳米钴粉的组成、平均粒径和产率的影响。X射线粉末衍射分析表明，纳米钴粉的平均粒径最小，为14 nm。
Nanocrystalline cobalt powders, consisting of a pure hexagonal phase, and a hexagonal phase mixed with a small amount of a cubic phase, have been prepared from aqueous solutions at ambient temperature and pressure by a γ-irradiation method. The influence of the experimental conditions on the composition, the average particle size and the yield of nanocrystalline cobalt powders has been studied in detail. X-Ray powder diffraction patterns show the smallest average particle size of the nanocrystalline cobalt powders to be 14 nm.
