· JVASP-27283· Ta2Hg3SO4F10

Ta2Hg3SO4F10 is an experimental mixed-metal ceramic compound containing tantalum, mercury, sulfate, and fluoride phases. This material belongs to the family of complex inorganic salts and fluoride-based ceramics, which are primarily of research interest rather than established industrial workhorses. While not widely deployed in production, materials in this compositional space are investigated for specialized applications requiring chemical stability, ionic conductivity, or unique crystal structures—particularly in solid-state electrolytes, optical materials, and corrosion-resistant coatings where the combination of heavy metals and fluoride anions can offer unusual property combinations.
