ceramic

· JVASP-36980· TlHgF3

TlHgF3 is a mixed-metal fluoride ceramic composed of thallium and mercury with fluorine, belonging to the halide ceramic family. This is primarily a research compound studied for its ionic conductivity and crystal structure properties rather than a widespread industrial material. While halide ceramics have potential in solid-state electrolytes and specialized optical applications, TlHgF3 remains largely experimental due to toxicity concerns with both thallium and mercury, limiting commercial adoption compared to safer fluoride alternatives.
