| 摘 要： | 在国产DS6×800A型六面顶压机上，对比研究了含与不含固溶碳的Ni-Mn粉末触媒，采用直热式静压触媒法合成金刚石的差异。实验表明：Ni-Mn粉末触媒中固溶碳的存在，不仅可以提高金刚石的合成单产、细化金刚石晶粒，而且在同工艺条件下，能得到晶形完整度较高的金刚石单晶。

| Abstract: | Effects of solution carbon in Ni Mn powder catalyst on diamond synthesis were investigated by using a cubic press.The behavior of the solution carbon in the synthesizing process was examined.Experiment results show that the solution carbon in the powder catalyst can increase not only the yields of diamond,enhance the synthesis efficiency,but also the nucleation rate,promoting the formation of better shape(perfect) crystals.A discussion of the mechanism of the effects of the solution carbon in the catalyst powder was presented. |

| Keywords: | powder catalyst shape of crystals synthetic efficiency solution carbon. |
