YbMgNiH4
metal· JVASP-51740· YbMgNiH4
YbMgNiH4 is an experimental metal hydride compound combining ytterbium, magnesium, nickel, and hydrogen. This material belongs to the ternary hydride family, which is primarily of research interest for hydrogen storage applications and fundamental studies of metal-hydrogen interactions. Though not yet commercialized, compounds in this family are investigated for energy storage systems and as model materials for understanding how hydride phases behave under pressure and thermal cycling.

Export Control
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
