| 摘 要： | 利用工业金刚石高压合成装置研究了C60和巴基管在高温（1 450 ℃）高压（5~6 GPa）下的相变。SEM、XRD和Uv/Vis分析结果表明，试样中有大量金刚石生成和少量石墨出现，同时有极少部分C60保留了下来；所生成的金刚石晶体同时以二维台阶和螺旋台阶方式生长。

| Abstract: | The phase transition of both C60 and Buckytube has been studied under high pressure up to 5～6 GPa and high temperature at 1 450 ℃ by cube equipment. The experimental results of SEM, X-ray and Uv/Vis show that most of the fullerene sample can transform to diamond with good crystal morphology, part transforms into graphite and a little has still been reserved. The transformed diamond crystal grows out of two-dimensional step and screwy step. |
