· JVASP-25616· K2ScSi4O10F

K2ScSi4O10F is a fluorine-containing silicate ceramic composed of potassium, scandium, silicon, oxygen, and fluorine. This material belongs to the family of complex silicates and represents a research-phase compound rather than a mature commercial ceramic. Scandium-bearing silicates are investigated for specialized applications requiring thermal stability, low thermal expansion, or unique optical properties, though this specific composition is not widely deployed in mainstream engineering. The inclusion of fluorine suggests potential interest in applications demanding corrosion resistance or specific electrochemical properties, though practical use cases remain limited to materials science research and potential emerging applications in advanced ceramics.
