Abstract:
A system and method for obtaining spherically symmetrical implosion of sample materials by directing radiant ignition energy (60) onto a target (10) which includes a spherically symmetrical core of selected sample material (12) concentrically surrounded. by a shell of high explosive material (14). The resulting implosive compression produces hydrodynamically controlled physical and/or chemical and/ or metallurgical transformations of state in the sample material (12).
Abstract:
A process for producing ultra-fine ceramic particles with the particle size of less than 1000 A, which comprises the steps of forming powdered dust cloud of metal powder such as Si constituting a portion of aimed ceramic particles in a reaction gas containing the other portion of said aimed ceramic particles, igniting said powdered dust cloud to cause explosive burning and synthesizing said aimed ceramic particles and gathering said resulting ceramic particles. By the process, ceramics particles such as Al 2 O 3 , MgO, SiO 2 , TiO 2 , TiN having particle size of 10 - 100 nm can be produced.

Abstract:
In this production method, to produce a carbon particle via the detonation method, an explosive substance having a detonation velocity of 6300 m/s or faster is disposed around a raw material substance containing an aromatic compound having two nitro groups or less, and the explosive substance is detonated. This production method allows carbon particles containing nano-scale graphite carbon and diamond to be produced via a detonation method using a non-gunpowder raw material. In addition, the obtained carbon particles have a G/D mass ratio of 2.5 or greater, where G is the graphite carbon mass and D is the diamond mass.
