Abstract
A method is disclosed for making graphenic carbon particles. The method includes introducing a hydrocarbon precursor material capable of forming a two-carbon-fragment species into a thermal zone, heating the hydrocarbon precursor material in the thermal zone to form the graphenic carbon particles from the hydrocarbon precursor material, and collecting the graphenic carbon particles. Apparatus for performing such a method, and graphenic particles produced by the method, are also disclosed.

A method for making graphenic carbon particles comprising:
- introducing a hydrocarbon precursor material capable of forming a two-carbon-fragment species into a thermal zone having a temperature of from greater than 3,500° C. to 20,000° C.;
- heating the hydrocarbon precursor material in the thermal zone to form the graphenic carbon particles from the hydrocarbon precursor material;
- and
- collecting the graphenic carbon particles, wherein at least a portion of the graphenic carbon particles comprise multiple stacked layers and the graphenic carbon particles have an average aspect ratio greater than 3:1.
