| 摘 要： | 选用工业生产的纳米SiC粉料；利用歧化反应原理，分解出Cu颗粒，并与纳米SiC颗粒组成分散均匀的复合粉体；SEM和Auger电子探针形貌显示复合粉体颗粒呈球形；EDS、AES等检测结果表明，金属Cu颗粒包覆在纳米SiC颗粒表面，从而使两相在纳米尺度范围内保持理想的均匀分散状态。

| Abstract: | Nano SiC particles in diameter of about 100nm were commercially available, Cu particles were precipitated during the disproportionation reaction process. The morphology of the mixed powders containing the nano SiC and Cu particles were observed by SEM or Auger micro-probe, in which the spherical particles dominated. EDS and AES were carried out to determine the element distribution in the local area and spot across a single particle. The coating process of Cu on the surface of the nano SiC particles ensures the homogeneous phase-distribution between the two different phases. |
