· JVASP-26362· KNb4O5F

KNb4O5F is a potassium niobium oxide fluoride ceramic compound that belongs to the family of mixed-anion oxyfluoride materials. This is a research-grade ceramic of potential interest for applications requiring fluoride-containing inorganic phases, though it remains primarily in the literature and experimental domain rather than established industrial production. The incorporation of fluoride into niobate structures can influence optical, thermal, and structural properties compared to conventional niobate ceramics, making it relevant for exploratory work in photonic materials, solid electrolytes, or specialty ceramic composites.
