Description
Satoshi Nakano and colleagues map where a hydrogen-carrying crystal phase stays stable in two hydrides, in a study from 2026. Barium and strontium hydrides can conduct hydride ions when hot or squeezed. So diamond-anvil presses with X-ray reads charted phase borders up to about 500 degrees and tens of gigapascals for both compounds.
The hot phase and the squeezed phase in barium hydride proved to be one phase, stable in its nickel-indium type frame up to about 50 GPa in the reported map. Strontium hydride took the same frame above 7 GPa, and squeeze stiffness values of 31.5 and 42.4 GPa were set for the pair, guiding future ion-flow studies.
