Abstract:

DESCRIPTORS Shock waves, Compression shock, Crystal structure, Diamonds, Graphite, High pressure research, Explosions, X-ray diffraction analysis, Production, Electron diffraction analysis, Samples of graphite have been recovered after exposure to explosive shocks of 300,000 atmospheres estimated intensity. X-ray and electron diffraction examinations prove the existence of diamond in this material. The mechanism proposed for the formation of diamond under these conditions is simple compression in the c-axis direction of the rhombohedral form of graphite. Author
