在超高压高温条件下,用 NiFeMn 合金作溶剂—催化剂,生长出晶形比较完整,粒径为1—1.8毫米左右的金刚石单晶。淬冷、卸压后取得的金属薄膜的最大厚度约0.1毫米。通过对金属薄膜作显微观察后发现,覆盖在{111}面上的较厚的金属薄膜常常可以分为三个亚层,邻接石墨区的富碳“过渡层”,以金属为主量的中间层和与金刚石相邻的富碳“过渡层”。用 JASCAL 语言编制电子计算机程序,控制 JCXA—733型电子探针,进行碳 KαX 射线光谱图
In the condition of ultra-high pressure and high temperature, NiFeMn alloy was used as solvent-catalyst to grow a diamond single crystal with more complete crystal shape and 1-1.8 mm diameter. Quenched and unloaded after the maximum thickness of the metal film obtained about 0.1 mm. Through the microscopic observation of the metal film, it is found that the thicker metal film covering the {111} plane can often be divided into three sublayers, the carbon-rich “transition layer” adjacent to the graphite region, and the metal-based Middle layer and the carbon-rich “transition layer” adjacent to the diamond. Using JASCAL language, a computer program was programmed to control the JCXA-733 electronic probe for carbon Kα X-ray spectroscopy
