【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.更多还原

【Abstract】 Industrial single crystal diamonds were synthesized from FeNi powder catalyst in a Chinatype cubic anvil high-pressure apparatus.In a series of experiments,we successfully synthesized highquality 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.更多还原
