Abstract
This invention relates to a production method for non-detonation synthesis nanodiamond by exposing carbonaceous feedstock to a dense plasma focus. The nucleated nanodiamond particles have characteristics that differentiate them from known forms of nanodiamond. For instance, the nucleated nanodiamond particles are substantially spherical and have a substantially smooth surface, as may be demonstrated by TEM. The nucleated nanodiamond particles are also free of graphite and detonation carbon contaminants. The identity of the nanodiamond particles has been confirmed through raman spectra, for example. The nanodiamond particles have also been found to be effective as a lubricant composition when combined with a carrier oil.
