· Y4 Si1 S3

Y₄Si₁S₃ is an yttrium silicon sulfide ceramic compound, representing a mixed-anion ceramic in the rare-earth chalcogenide family. This material is primarily of research interest rather than established in high-volume production, with potential applications in solid-state ionics, thermal management, and advanced ceramic coatings where rare-earth sulfides offer unique electrochemical or thermal properties distinct from conventional oxides.
