Tb5 Se2 Cl3 O10

Tb₅Se₂Cl₃O₁₀ is a rare-earth oxyhalide ceramic compound combining terbium with selenium, chlorine, and oxygen—a complex composition that places it in the family of lanthanide halide oxides. This is primarily a research material under investigation for photonic, luminescent, or electronic applications rather than an established commercial ceramic, with the mixed halide-oxide structure offering potential for tunable optical or solid-state properties not easily achieved in simpler ceramic systems.
