The room tempearture equations of state of the metallic hydrides NiH<SUB>x</SUB> and ReH<SUB>x</SUB> have been studied to 123 GPa and of the nonmetallic hydrides AIH<SUB>3</SUB>/AID<SUB>3</SUB> to 53 GPa by means of x-ray diffraction in a diamond anvil cell. The partial hydrogen volume in ALH<SUB>3</SUB>/AlD<SUB>3</SUB> 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.
