Zirconium Hydride: Structural Integrity at High-Pressures - A Synchrotron X-Ray Difffraction Study

ORAL

Abstract

Metal hydrides are of great interest not only form the fundamental research point of view but also because of their many technological applications, including hydrogen storage. Here we present our most recent studies in situ, high-pressure, angle-dispersive, synchrotron x-ray diffraction studies of zirconium hydride. We investigate the effects of hydrostatic and non-hydrostatic conditions. We also show the results of structural refinements as well as the bulk modulus of ZrH2. *Work at UNLV is supported by DOE award No. DEFG36-05GO0850.
