· JVASP-12875· RbBS3

RbBS₃ is an inorganic ceramic compound composed of rubidium, boron, and sulfur, representing a borate sulfide ceramic in the broader family of mixed-anion ceramics. This material is primarily of research interest rather than widespread commercial use, studied for its potential in optical, electronic, or structural applications where borate-sulfide ceramics offer unique combinations of properties unavailable in conventional oxide ceramics. RbBS₃ and related compounds are investigated for applications requiring thermal stability, chemical inertness, or specific optical/electronic functionality in specialized engineering environments.
