静压法高石墨转化率的金刚石合成研究

RESEARCH ON THE HIGH TRANSFORMATION RATIO OF GRAPHITE TO DIAMOND BY THE STATIC PRESSURE METHOD

选用ＮｉＭｎＣ粉末触媒，在国产ＤＳ６×８００Ａ型铰链式六面顶压机上实现了高石墨转化率的金刚石合成，其石墨转化率可达９０％以上。高石墨转化率金刚石的合成，不仅有助于提高金刚石的效率，而且还可以减化提纯后处理工序。

Catalystic materials play an important role in the diamond synthesis.It can reduce the pressure and temperature required to transform graphite into diamond.By using Ni Mn C powder catalyst,the diamond synthesis with a transformation ratio of 90% from graphite has been achieved in this paper.
