摘要: 采用γ射线辐照可溶性Co盐溶液可制备金属Co超细微粒及其相应粉体.X射线衍射、电子衍射及相应的TEM形貌分析表明，金属粒子呈现各向异性生长的结晶体，当用醋酸Co作为出发原料，被辐照溶液浓度在0.005－0.2mol／L的范围内，辐照剂量和pH分别在2.3×104-3.9×105Gy和6.0-10.0时，超细粒子的平均粒径一般都在30nm左右.

关键词 ：金属Co超细粉, γ射线辐照, 微波辐照

Abstract：Ultrafine particles and powders of metallic α-Co were prepared in an aqueous solution of Co2+ by γ-ray radiation. The ultrafines appear as nanocrystallined particles according to X-ray and electron diffraction. The average size of particles is 30 nm while concentration of cobalt acetate solution, irradiation dose and solution pH are in the range of 0.005-0.2 mol / L, 2.3×104-3.9 ×105 Gy and 6.0-10.0 respectively.

Key words： α-Co ultrafine particle γ-ray radiation microwave radiation
