· JVASP-2880· Rb2HgF4

Rb2HgF4 is an inorganic fluoride ceramic compound composed of rubidium, mercury, and fluorine elements. This material belongs to the class of metal fluoride ceramics, which are primarily of research interest for specialized applications in electrochemistry and solid-state ionics rather than established commercial use. The compound's potential relevance lies in its ionic conductivity properties within the fluoride ceramic family, making it a candidate for exploratory work in solid electrolytes and ion-conducting ceramics, though it remains largely confined to academic investigation rather than mainstream industrial application.
