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.
