Nanoscale diamond particles and method of forming nanoscale diamond particles

摘要

A method of forming nanoscale diamond particles comprises providing C₂ and CH radicals at a low pressure, and nucleating the C₂ and CH radicals to form carbon nanoparticles comprising a diamond phase and a non-diamond phase. The method further comprises removing at least a portion of the non-diamond phase in flight during the nucleation of the C₂ and CH radicals to form a carbon powder comprising a plurality of nanoscale diamond particles.
