摘要
介绍了利用机械－物理固相效应制备纳米Ｎｉ粉，并用Ｘ射线衍射、透射电镜技术检测了它的微观结构，属于面心立方的金属Ｎｉ，粉末呈单晶和多晶簇团共存。这种制备纳米粉末的装置简便，易于建造，投资少，可用于金属、氧化物纳米粉末的工业生产。
By means of the mechanic-physical solid state effects，the nanometer nickel powder hasbeenprepared．The powder exhibits the states of monocrystal and polycrystal which wereidentified by X-ray diffraction and TEM electron diffraction.The usage of device is simpleand convenient at low prices.The mode of production can be used to prepare the powder ofmetal and mixture.
