The growth of amorphous carbons was performed at atmospheric pressure using a high voltage pulsed power supply (20 kV and 25 kHz) under the methane flux. Pulsed discharges of methane gas at atmospheric pressure were generated using high voltage power supply. The pulsed discharge of methane gas was generated between two sharp wolfram electrodes. Three types of carbon was produced by this pulsed plasma namely powder carbon, soft and hard carbon. Carbon samples were investigated by Scanning Electron Microscopy, Energy Dispersive X-ray spectroscopy and X-ray diffraction. The carbon samples have amorphous structure according to XRD results without contamination according to EDX results

The pulsed discharge of methane gas was generated between two sharp wolfram electrodes. It brings out carbon and acetylene and other hydrocarbons at the same time. In this study, carbon samples are produced and some of the physical properties of them were analyzed. The production rate of carbon was also determined. Carbon samples were investigated by Scanning Electron Microscopy, Energy Dispersive X-ray spectroscopy and X-ray diffraction. The produced carbon samples have amorphous structure according to XRD results and include no contamination according to EDX results. The samples have the strongest peak at 26.516 degrees at XRD spectra. Production rate is 0.52 mg/min at d (discharge space) being 8 mm and (flux of the methane gas) is 0.31/minrealized using devices of the Scientific Research Committee of Eskisehir Osmangazi University [200319009]This research activity was realized using devices of the Scientific Research Committee of Eskisehir Osmangazi University under the project number 200319009.
