· JVASP-7751· Tb2SO2

Tb2SO2 is a rare-earth sulfide-oxide ceramic compound combining terbium with sulfur and oxygen, representing an experimental material in the rare-earth ceramic family. While not widely established in mainstream industrial production, this compound is of interest in materials research for applications requiring high stiffness and density in chemically stable ceramic matrices, particularly where rare-earth dopants or mixed-anion ceramics offer advantages over conventional oxides. The material's composition places it at the intersection of sulfide and oxide ceramics—a research domain exploring new refractory, electronic, or optoelectronic properties unavailable in single-anion systems.
