摘要:
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.
摘要:
Disclosed are methods for making ultrafine particles. These methods include (a) introducing a plurality of precursors to a high temperature chamber, the precursors including a first precursor and a second precursor different from the first precursor and comprising an alkali metal dopant; (b) heating the plurality of precursors in the high temperature chamber, yielding a gaseous product stream; (c) quenching the gaseous product stream, thereby producing ultrafine particles; and (d) collecting the ultrafine particles. Also disclosed are apparatus for the production of ultrafine particles, ultrafine particles produced from a plurality of precursors and coating compositions and coated substrates that include ultrafine particles.

摘要:
A system and method for making ultrafine particles are disclosed. A high temperature plasma is generated at an inlet end of a plasma chamber into which precursor materials are introduced. A converging member is located adjacent an outlet end of the plasma chamber. During operation, a substantially constant pressure and/or material flow pattern is maintained to reduce or eliminate fouling of the system.
