· JVASP-35665· MgNiH3

MgNiH3 is a ternary metal hydride compound combining magnesium, nickel, and hydrogen, belonging to the intermetallic hydride family. This material is primarily of research interest for hydrogen storage and energy applications, where its ability to reversibly absorb and release hydrogen makes it relevant to next-generation fuel cell systems and portable power solutions. Unlike conventional hydrides, nickel-containing ternary systems offer tuned thermodynamic properties that can improve hydrogen cycling performance compared to binary magnesium hydrides.

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.
