· JVASP-57570· TbCl2F

TbCl₂F is a rare-earth halide ceramic compound combining terbium with chloride and fluoride anions. This material belongs to the family of mixed halide ceramics, which are primarily of research interest for specialized optical, magnetic, and electronic applications rather than established industrial use. Terbium-based compounds are investigated for luminescent materials, magnetic refrigeration systems, and potential high-temperature ceramic applications, though TbCl₂F specifically remains largely in the experimental phase with limited commercial deployment.
