| 摘 要： | 本文研究了添加剂Si对NiMnCo粉末触媒合成金刚石生长特性的影响.实验中将不同比例的无定形Si粉直接添加到Ni-Mn-Co-C体系中并均匀混合,在国产六面顶压机上进行了金刚石单晶的合成实验.结果表明,由于掺Si量的不同,合成金刚石的最低生长压力有所不同,"V"形区发生了移动;通过考察Ni-Mn-Co-C和Ni-Mn-Co-Si-C两种体系中合成金刚石的情况并借助于光学显微镜,发现两种体系所合成的晶体颜色变化并不大,但随着Si含量的增加,晶体的完整性变差,包裹体增多;通过XPS检测发现,在Ni-Mn-Co-Si-C体系所合成的金刚石当中存在SiC.

| Abstract: | The effect of additive Si on the growth character of diamonds synthesized using Ni-Mn-Co powder catalyst has been studied in this paper.Different content of amorphous Si powder was directly added to Ni-Mn-Co-C system and then the system was uniformly mixed.The synthesis experiments were carried out in a cubic anvil high-pressure apparatus.The results indicate that the minimum pressures for diamond formation changed with the difference of Si content,so did the position of V-shape region.The diamond synthesis... |
