本文用装配 X 射线波谱仪和 X 射线能谱仪的 JSM535C 扫描电镜对我院研制的部分金刚石产品、合成棒及触媒合金进行了研究,结果表明:1.在 SEM 衬度效应下能显示针状金刚石表面鱼骨状显微结构,其(111)生长面呈平行台阶状,台阶宽约10μm。在合成棒纵断面上观察到针状金刚石首先在触媒合金与石墨交界面处成核,然后向石墨内部平行生长,最后在 In this paper, with the assembly of X-ray spectrometer and X-ray energy dispersive spectrometer JSM535C scanning electron microscopy of some of the diamond products developed in our hospital, the synthesis of rods and catalyst alloys were studied. The results show that: 1. Under SEM contrast effect can show acicular Diamond surface fishbone microstructure, the (111) growth surface was parallel to the step-like, step width of about 10μm. In the synthetic rod longitudinal section observed acicular diamond first nucleation at the interface of the catalyst alloy and graphite, and then parallel to the graphite growth, and finally in
