· JVASP-100590· KRb2AsF6

KRb₂AsF₆ is an inorganic ceramic compound belonging to the family of complex fluoride salts, specifically a double fluoride with potassium, rubidium, and arsenic components. This material is primarily of research and specialized industrial interest rather than a high-volume commodity ceramic. It is investigated for applications in solid-state chemistry, optical materials, and specialized electrolytes where its crystalline structure and chemical stability in fluoride-rich environments offer potential advantages over conventional ceramics.
