· JVASP-35462· Rb2ZnF4

Rb₂ZnF₄ is an inorganic fluoride ceramic compound combining rubidium, zinc, and fluorine elements, belonging to the family of metal fluorides investigated for specialized optical and electrochemical applications. This material is primarily explored in research contexts for ionic conductivity and optical transparency in extreme environments, with potential use in solid-state electrolytes, fluoride-based laser hosts, and high-temperature windows where conventional ceramics or glasses are inadequate. Its fluoride composition makes it notable among ceramic alternatives for applications requiring exceptional chemical resistance and low refractive index in harsh conditions, though industrial adoption remains limited compared to established ceramic families.
