Abstract:Under 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.
