· JVASP-32781· AlB3H12

AlB3H12 is an aluminum boron hydride compound belonging to the metal hydride family, characterized by a complex ternary composition that combines lightweight aluminum with boron and hydrogen. This material is primarily of research and developmental interest for hydrogen storage and advanced aerospace applications, where its low density and potential for reversible hydrogen release make it relevant to emerging clean energy and lightweight structural programs. Compared to conventional aluminum alloys, AlB3H12 represents an experimental direction for enhancing energy density in mobile applications, though industrial adoption remains limited pending demonstration of thermal stability, cycling durability, and cost-effective synthesis routes.
