A new phenomenon involving the formation of liquid mobile metal–carbon particles in the low-temperature catalytic graphitisation of amorphous carbon by metallic Fe, Co and Ni
Abstract:
The reaction of Fe, Co and Ni with amorphous carbon and its catalytic graphitisation at relatively low temperatures (600–700 °C) in vacuo is accompanied by the formation of liquid mobile metal–carbon (M–C) particles; the mechanism by which these particles are formed and maintained in the liquid state is suggested.
