ceramic

· JVASP-21612· Sm10S19

Sm₁₀S₁₉ is a rare-earth sulfide ceramic compound belonging to the lanthanide chalcogenide family, combining samarium with sulfur in a defined stoichiometric ratio. This material is primarily of research and specialized interest, explored for applications requiring rare-earth ionic conductivity, optical properties, or high-temperature stability in sulfide-based systems. It represents the broader class of rare-earth sulfides investigated for solid-state ionics, luminescent devices, and high-temperature structural applications where conventional oxides may be unsuitable.
