Into the Mechanism of Diamond Formation

It is clear that all these results give only indirect evidence for the mechanism of diamond formation in detonation of explosives. In order to confirm the hypotheses suggested above, experimental evidence is necessary. Because of the complexity of detonation products, the veiy short duration of the detonation process, and the veiy high pressure and temperature in the detonation zone of 

The ultrafine diamond obtained by explosive detonation possesses two distinguishing features nano-scaled particle sizes and surface functional groups. 

It is interesting to mention that, after treating the solid detonation products with oxidative acid and followed by washings with water, a very stable slurry of diamond particles in water is obtained, which contains only 7-10 wt% of diamond. This slurry can remain stable for a long time, months, even years. Referring to the TEM images, it is proposed that the stable slurry is composed of 

Application of ultrafine diamond is a special field and to discuss it in detail is beyond the scope of this chapter, so only a brief account is given. 

The ultrafine diamond was also used as seed to prepare CVD diamond films. This led to a significant increase in the growth rate and the density of nucleation
