Formation of Diamond by Explosive Shock
P. S. Decarli,John C. Jamieson +1 more
TL;DR: X-ray and electron-diffraction examinations prove the existence of diamond in this material and 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.
Journal ArticleDOI
Crystal Structures at High Pressures of Metallic Modifications of Silicon and Germanium
TL;DR: Studies of germanium and silicon by x-ray diffraction reveal that their crystal structure changes at high pressures from the semiconducting diamond-type structure to the metallic white tin structure, in analogy to the known "gray to "white" transition in tin itself.
Journal ArticleDOI
Crystal Structures of Titanium, Zirconium, and Hafnium at High Pressures
TL;DR: At high pressures, as determined by x-ray analysis, titanium and zirconium metal have a distorted, body-centered-cubic structure that persists on pressure release and an electronic shift must occur in the transition.
Journal ArticleDOI
Crystal Structures Adopted by Black Phosphorus at High Pressures
TL;DR: The reversibility between the A7 and simple cubic structures at 111 kilobars indicates that the transition obtainable at this pressure provides a good calibration point by which high-pressure x-ray data may be united with volumetric or resistance measurements, or both.
Journal ArticleDOI
Shock-wave compression and x-ray studies of titanium dioxide.
TL;DR: The Hugoniot of the rutile phase of titanium dioxide has been determined to 1.25 megabars, and data show the existence of a phase change at about 0.33 megabar, suggested that the new phase may be another diagnostic indicator of meteorite impact on the earth's surface.
