· JVASP-10460· NaLi2AsO4

NaLi₂AsO₄ is a mixed-metal arsenate ceramic compound combining sodium, lithium, and arsenic oxide constituents. This material belongs to the family of alkali metal arsenates and remains primarily a research-phase compound studied for potential applications in solid-state chemistry and materials engineering. The combination of alkali metals with arsenic oxide provides unique crystal structure and ionic transport characteristics that distinguish it from conventional oxide ceramics, though industrial deployment remains limited and applications are largely exploratory.
