Notes:
We have attempted phase identification of carbon nanosized powders prepared by pulsedwire discharge (PWD) to clarify the cooling process of PWD plasma. To prepare the carbonnanosized powders, carbon fibers were discharged in nitrogen gas at 26 – 101 kPa by PWD. Volumefractions of phases in the carbon nanosized powders were analyzed by thermogravimetric analysis andpowder X-ray diffraction. The volume fraction of amorphous carbon, which must be formed byquenching of carbon plasma, was increased with increasing nitrogen gas pressure. This resultsuggested that the cooling rate of PWD plasma increased with increasing ambient gas pressure
