· JVASP-62771· MgB2H8

MgB2H8 is a magnesium borohydride ceramic compound that belongs to the family of complex metal hydrides with potential energy storage and structural applications. This material is primarily of research interest rather than established in high-volume production, with investigations focused on hydrogen storage capability and lightweight structural behavior for aerospace and advanced energy systems. The compound's low density and ceramic character make it a candidate for next-generation lightweight materials where hydrogen-rich systems could provide dual functionality in energy and structural roles.
