在直流恒稳强磁场(10 T)作用下,以纳米铁为催化剂,碳黑为碳源,在常压和1100℃下保温100 min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20 nm,石墨包覆新金刚石的大小为100 nm.

关键词: 强磁场, 催化剂, 类金刚石, 碳黑

Under a static high magnetic field of 10 T, diamond-like carbon (DLC) nanocrystals and n-diamond particles have been synthesized at atmospheric pressure and 1100℃, 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.

Key words: high magnetic field, catalyst, diamond-like carbon, carbon black
