摘要: In situ x-ray diffraction experiments on rhenium hydride compressed up to 46 GPa reveal a hydrogen solubility (x) significantly larger than the previously assumed saturation limit of x ~ 0.38(4). layered anti-CdI(2)-type structure hydride, was found increase 0.5 at 15 over time. When heated temperatures above 420 K pressures 23 GPa, undergoes an isomorphous phase transition into NiAs-type accompanied by in 0.85. The formation fully stoichiometric is discussed.
