· JVASP-51707· Li4H6Os

Li₄H₆Os is an experimental ceramic compound combining lithium, hydrogen, and osmium—a research-phase material that does not have established commercial production or widespread engineering adoption. This material belongs to the family of complex hydride ceramics and intermetallic compounds, which are of interest in materials science for their potential combinations of light-weighting (via lithium) and high-density phases (osmium). The compound remains primarily in laboratory investigation; potential future relevance would depend on discoveries in hydrogen storage, catalytic applications, or specialized high-performance ceramic matrices, though current practical applications are not documented in mainstream engineering practice.
