摘要:

利用FeNi粉末触媒在六面顶压机上进行工业金刚石单晶的合成与表征. 结果表明: 在Fe-Ni-C体系合成了优质的六面体、 六-八面体及八面体金刚石单晶; 金刚石{111}晶面的生长属于二维层状生长机制; 金刚石中的包裹体主要由FeNi合金组成.

Abstract:

Industrial single crystal diamonds were synthesized from FeNi powder catalyst in a Chinatype cubic anvil highpressure apparatus. In a series of experiments, we successfully synthesized highquality cubic, cubicoctahedral and octahedral diamond single crystals. From the morphology of the synthesized diamond, we found the {111} plane obeyed the  twodimensional layer growth mechanism. The Mssbauer spectra indicate that the main components of the impurity are FeNi alloy in the diamond.

Key words: diamond, catalyst, morphology
