· JVASP-125879· RbK3

RbK3 is an intermetallic ceramic compound composed of rubidium and potassium, belonging to the alkali metal ceramic family. This material exists primarily in research and specialized applications due to its unique ionic bonding characteristics and light density. It is notable for potential use in solid-state electrochemistry, alkali-metal-based energy systems, and theoretical materials studies where conventional ceramics cannot provide the required alkali metal functionality.
