| 摘 要： | 研究高温高压下掺Si合成金刚石, 并与Fe-C体系合成的金刚石进行比较. 实验结果表明, 体系中掺入Si, 合成的晶体颜色比Fe-C体系合成的晶体颜色浅, 在相同的合成时间内, Fe-Si-C体系合成金刚石的粒度比Fe-C体系合成金刚石的粒度小; 通过X射线衍射(XRD)可见, 该体系产生FeSi和Fe3C两种新物质.

| Abstract: | By high pressure and high temperature (HPHT) method, the study on introducing Si into diamond synthesis was carried out. Experimental results indicate that owing to the introduction of Si, the color of diamonds from Fe-Si-C system appears to be shallower than that from Fe-C system. And within the same synthetic time, the crystal size of diamonds from Fe-Si-C system is smaller than that from Fe-C system. From X-ray data, we can find that there are two kinds of new compounds, FeSi and Fe3C, in the Fe-Si-C system. |
