The Amount of Impurity Elements in Diamond-Containing Soot and Detonation Nanodiamonds upon Nitric Acid Treatment

Аннотация

The influence of the explosive charge shell composition and the explosive charge modification by various compounds on the yield of DND and DS, content of impurities and their elemental composition has been studied. With proper choice compounds, one can increase the DS yield to 18.6 wt % and the DND yield to 7.6 wt %, reduce the amount of impurities down to 0.23 wt % in DS and to 0.3 wt % in DND. The phosphorus concentration was brought to 0.665 wt % in DS and to 0.244 wt % in DND; the boron content was brought to 0.96 wt % in DS and to 0.472 wt % in DND.
