· JVASP-7755· Lu2SO2

Lu2SO2 is a rare-earth sulfur oxide ceramic compound combining lutetium (the densest lanthanide) with sulfur and oxygen. This material belongs to an emerging class of rare-earth compounds with potential applications in high-performance ceramics and specialty refractory materials. As a research-phase compound rather than a widely commercialized engineering ceramic, Lu2SO2 is primarily of interest in academic materials science and advanced ceramics development, where its dense structure and rare-earth chemistry may enable thermal stability, radiation resistance, or specialized optical properties in extreme environments.
