چکیده انگلیسی
Polyhedral graphite (PG) particles that have a structure composed of many polyhedra with 100â¯nm â1â¯Î¼m diameters were formed by using a modified arc discharge method (high-density carbon arc discharge method). The high-density carbon arc discharge was maintained by pyrolysis of ethanol during sublimation of a carbon anode. In this study, we investigated the most effective conditions for forming PG particles in high-density carbon arc plasma with ethanol vapor. We found that diameters of PG particles depended on arc current and that PG particles were effectively formed by using the high-density carbon arc discharge method. Furthermore, results of heat treatment at 2000â¯Â°C indicated that the obtained PG particles were graphitized well and that surfaces of the particles with diameters over 400â¯nm tended to peel off. Compared with the conventional laser vaporization method, the newly developed high-density carbon arc discharge method does not require an expensive equipment and high-pressure atmosphere gas, and is easy to scale up for mass production of PG particles.
