摘    要:
 本文介绍了对合成金刚石用石墨片进行预处理的方法。研究表明,用已处理过的石墨片合成出粒度组、强度高、完整单晶多的金刚石,金刚石中Ni、Mn、Co、Si的含量明显减少,而氮的含量明显增加。并观察到触媒片两面都能均匀地生长理想的金刚石晶体。该预处理方法不仅提高金刚石的质量,而且有可能为认识石墨转化为金刚石的机理提供一些依据。

关 键 词:金刚石  触媒  石墨片

Abstract:
This paper reports the effect of pretreatment of graphite on the diamond growth. Big size diamonds of good quality were synthesized, in which the inclusions of Ni. Mn. Co. Si were reduced and N content increased. It was found that the diamond grew on both side of catalytic disks. The pretrealmem method not only improved the quality of diamond, hut also might provide basis for understanding of the mechanism of graphite transformation to diamond.
Keywords:diamond   catalyst   graphite.
