摘　　要：在直流恒稳强磁场 ( 10T)作用下 ,以纳米铁为催化剂 ,碳黑为碳源 ,在常压和 110 0℃下保温 10 0min成功地制备出了类金刚石和新金刚石 ,并用XRD ,TEM和Raman对制备的样品粉末进行表征 .结果表明 ,样品粉末是由纳米类金刚石粉和石墨包覆新金刚石纳米颗粒组成 ,纳米类金刚石粉的大小为 2 0nm ,石墨包覆新金刚石的大小为 10Under a static high magnetic field of 10 T, diamond-like carbon (DLC) nanocrsytals and n-diamond particles have been synthesized at atmospheric pressure and 1100 degreesC. with carbon black as carbon source and nanometer-sized iron as catalyst. X-Ray diffraction, Raman, transmission electron microscopy, and electron-probe microanalysis methods were used to analyze the product. The results indicated that the average Size of the DLC nano powders is about 20 nm, and that of the graphite-coated n-diamond particles is about 100 nm.
