为了获得混合均匀的UN、U₃Si₂混合粉体，采用行星式球磨机对UN以及U₃Si₂粉体进行球磨处理。然后采用X射线衍射仪(XRD)分析不同U₃Si₂含量的UN、U₃Si₂混合粉体的物相。结果表明，球磨后的混合粉末主要为UN相和U₃Si₂相，其中以UN相为主要物相。U₃Si₂的衍射峰强度明显低于UN的衍射峰强度，并且随着U₃Si₂含量的增加，U₃Si₂相衍射峰强度并未有明显增加。

To obtain uniformly mixed UN and U₃Si₂ powders, the UN and U₃Si₂ mixed powders with different U₃Si₂ content was ball milled by planetary ball mill. Then, the phase of the mixed UN and U₃Si₂ powders were characterized by X-ray diffractometer (XRD). The results show that the mixed powders after ball milling contain UN phase and U₃Si₂ phase, and the main phase of the mixed powders is the UN phase. The diffraction peak intensity of U₃Si₂ phase was significantly lower than that of UN phase. Furthermore, the diffraction peak intensity of U₃Si₂ phase did not increase significantly with the increase of U₃Si₂ content.
