ceramic

· JVASP-86112· KNaB2H8

KNaB2H8 is a light ceramic compound belonging to the borohydride family, combining potassium and sodium metal cations with borohydride anions. This material is primarily of research and developmental interest rather than established in high-volume industrial production; it is studied for its potential as a solid-state hydrogen storage medium and as a constituent in advanced inorganic electrolytes for next-generation battery systems. The compound's low density and ionic bonding structure make it attractive for applications requiring hydrogen-rich ceramics or solid electrolytes, though practical deployment remains limited to laboratory and prototype-stage development.
