· JVASP-51717· Mg2H4Ru

Mg2H4Ru is a complex hydride ceramic compound combining magnesium, hydrogen, and ruthenium, representing a specialized class of metal hydride materials studied primarily in research contexts rather than established commercial production. This material belongs to the family of transition metal hydrides and intermetallic compounds, with potential applications in hydrogen storage, catalysis, and advanced energy systems where ruthenium's catalytic properties combined with magnesium's lightweight characteristics are leveraged. The compound is notable in materials science research for exploring new pathways in hydrogen-based energy technologies and demonstrates the type of engineered ceramic-metallic hybrid that emerges from combinatorial materials discovery in sustainable energy applications.
