Some Important Research Topics Concerning Ultrafine Diamond from Explosive Detonation... 

Explosives, as a special kind of material, can produce a special state of materials—detonation. In a long historical period of time, explosives have been used for the purposes of destruction, elimination, or decomposition, and these purposes still account for the main utilization of explosives. In recent years it has been found that explosives can be used for the opposite purposes of construction, creation, and synthesis. Using the high pressure, high temperature and high mass speed produced by explosive detonation, new substances or substances with unique features can be produced. Two examples are given in this chapter shock-wave-induced chemical reactions for material synthesis and ultrafine diamond synthesized by explosive detonation. Much research work has been done in these fields in recent years, but the quantity and the depth of these studies are far from sufficient. There remain many unsolved problems and unexplored fields.
