摘    要:本文分别用铁镍触媒、含添加剂硫的铁镍触媒在国产六面顶压机上合成了优质金刚石单晶,利用光学显微镜观察,发现所合成的金刚石多为六八面体,晶形完整;在大多数用含添加剂硫的铁镍触媒合成的金刚石的{100}面,有熔坑出现,而用铁镍触媒合成的金刚石没有这种现象;用电子显微镜对熔坑的形貌进行了细致的观察。另外,还发现用含添加剂硫的铁镍触媒合成的金刚石中的包裹体要明显少于用铁镍触媒合成的金刚石中的包裹体。

关 键 词:铁镍触媒    熔坑  包裹体

Abstract:In this paper, high quality diamond crystals were synthesized respectively using Fe - Ni catalyst and Sulfur-added Fe - Ni catalyst in cubic anvil high-pressure apparatus. The synthesized diamond crystals are observed to be with integrated cubo -octahedral shape under optical microscope. Some etch pits were observed on {100} face of the most diamond crystals which are synthesized with sulfur-added Fe - Ni,while no etch pit in the diamond synthesized without sulfur additive. We also observed the etch pits under scanning electron microscope ( SEM). In addition, we noticed that the content of inclusion in the diamond crystals synthesized with sulfur - added Fe - Ni is obviously lower than that in the diamond synthesized without additive.
Keywords:Fe-Ni catalyst  sulfur  etch pits  inclusion
