在20（1）GPa和2000 ℃下使用多砧装置由富勒烯C-60合成具有5-12 nm晶粒尺寸的纳米晶立方金刚石的块状样品。这种新材料至少和单晶金刚石一样坚硬。结果发现，纳米金刚石在高温和环境压力动力学更稳定的石墨化比普通的金刚石。(C)2004 Elsevier B. V.保留所有权利。
A bulk sample of nanocrystalline cubic diamond with crystallite sizes of 5-12 nm was synthesised from fullerene C-60 at 20(1) GPa and 2000 degreesC using a multi-anvil apparatus. The new material is at least as hard as single crystal diamond. It was found that nanocrystalline diamond at high temperature and ambient pressure kinetically is more stable with respect to graphitisation than usual diamonds. (C) 2004 Elsevier B.V.
