· JVASP-10796· Ag2SeO4

Silver selenate (Ag₂SeO₄) is an inorganic ceramic compound composed of silver, selenium, and oxygen. This material belongs to the family of metal selenates and is primarily investigated in research contexts for its potential in ion-conducting applications, photocatalysis, and solid-state chemistry rather than as an established commercial engineering material. Its layered crystal structure and moderate density make it of interest to materials scientists exploring alternatives in electrochemical devices and optical applications, though industrial adoption remains limited compared to more conventional ceramic systems.
