ceramic

· JVASP-11187· Rb2LiAsO4

Rb2LiAsO4 is an inorganic ceramic compound containing rubidium, lithium, and arsenate ions, belonging to the family of mixed-metal oxysalt ceramics. This is a research-phase material studied primarily for its potential in solid-state ion conductivity and electrochemical applications rather than a widely commercialized engineering ceramic. The lithium-containing composition suggests investigation as a solid electrolyte or ion-conducting medium for advanced battery and electrochemical device development, where alternatives like yttria-stabilized zirconia or perovskite phases are more established.
