· JVASP-51734· Yb4Mg3H14

Yb4Mg3H14 is a ytterbium-magnesium hydride ceramic compound, part of the rare-earth metal hydride family that combines lightweight magnesium with ytterbium to form a hydrogen-storage or intermetallic ceramic phase. This is a research-stage material rather than a commercial product; the hydride chemistry suggests potential applications in hydrogen storage systems, solid-state battery components, or advanced structural ceramics where the combination of light weight and rare-earth stabilization could offer benefits. Compared to conventional ceramics, this material family is investigated for its potential to enable safer hydrogen handling, improved ionic conductivity in energy storage devices, or enhanced mechanical properties through controlled hydride phases.
