Abstract

The room tempearture equations of state of the metallic hydrides NiH₂ and ReH₂ have been studied to 123 GPa and of the nonmetallic hydrides AIH₃/AID₃ to 53 GPa by means of x-ray diffraction in a diamond anvil cell. The partial hydrogen volume in ALH₃/AID₃ is found to reduce to that characteristic of metallic hydrides at ~ 47 GPa. The evolution of the partial hydrogen volume with pressure in the metallic hydrides is discussed in light of existing empirical models.
