· Rb2SiS3

Rb₂SiS₃ is a rare-earth silicate sulfide ceramic compound belonging to the family of mixed-anion ceramics that combine silicate and sulfide chemistry. This material is primarily of research and exploratory interest rather than established industrial production, investigated for its potential in solid-state ionic conduction and advanced ceramic applications where thermal stability and unique ionic transport properties may be advantageous.
