摘　　要：为了获得在自然条件下稳定存在的超细镍粉,通过控制行星式高能球磨机的转速、研磨时间、磨球数、运转时间、暂停间隔、转动方向等参数对镍粉进行了研磨实验,并对不同参数下的研磨结果进行了测试表征。结果表明,在转速260 r/min、研磨时间19 h、运行时间3 min、暂停时间30 s、磨球数为10个、原料5 g且晴朗天气下实验,可以制备出亚微米级超细镍粉,并在空气中稳定存在。In order to obtain stable ultrafine nickel powder under natural conditions,the nickel powder grinding test was performed by controlling the speed,grinding time,the number of balls,running time,the suspension of spacing,rotation and other parameters of planetary high energy ball mill.Grinding results of different parameters were characterized.Results show that the submicron level of ultrafine nickel powder with stable state in the air can be prepared on sunny weather when the speed is 260 rpm and grinding time is 19 h with run time of 3 min,pause time of 30 s,the ball number of 10 and 5 g of raw materials.
