· JVASP-10141· Hg3S2F2

Hg₃S₂F₂ is a mercury-based ceramic compound combining mercury, sulfur, and fluorine in a crystalline structure. This material belongs to the family of mixed-halide and chalcogenide ceramics, primarily of research interest rather than established industrial production. While applications remain largely experimental, mercury-containing ceramics have been investigated for specialized optical, electrochemical, and high-density ceramic applications where the unique electronic properties of mercury compounds offer potential advantages over conventional alternatives.
