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（１４５０℃）高压（５～６ＧＰａ）下的相变。ＳＥＭ、Ｘ－ｒａｙ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。The phase transition of both C60 and Buckytube has been studied under high pres-sure up to 5～6GPa and high temperature at 1450℃ by cube equipment.The experimental resultsof SEM,X-ray and Uv/Vis show that most of the fullerene sample can transform to diamondwith a 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.
