摘要
本文用拉曼探针研究了湖南金刚石矿砂中的天然金刚石，发现在某些金刚石中含有硅，确定硅是以ＳｉＣ的立方晶系形式存在的．并认为Ｓｉ可能也是以这种结构形式存在于人工金刚石中。
In this paper, natural diamonds placer in Hunan Province have been studied by means of Raman Microprobe. There are silicon elements in some diamonds. The existing form of the silicon in the silicon-diamonds is disordered cubic SiC. Moreover, we think that the existing form of the silicon in the manmade diamonds may be disordered cubic SiC as well.
