摘　　要：研制了直流电弧等离子体球化U3 Si2 粉体装置。在Ar +He气氛下对粒度为 1 0～ 1 5 0 μm范围内不规则形状的U3 Si2 粉体进行了球化。球化率达 90 %。The device for sphericized U 3Si 2 powder by direct current arc plasma was fabricated.In Ar and He mixture plasma atmosphere.The spherical U 3Si 2 powder was produced from irregular powder in the range of 10～150 μm.The result shows that the conversion rate of the U 3Si 2 powder could reach 90%.
