Ca₂SiB₂O₇ is an oxyborate ceramic compound combining calcium silicate and borate phases, belonging to the family of silicate-borate ceramics. This material is primarily investigated in research contexts for high-temperature applications and specialized glass-ceramic compositions, where the borate component enhances densification and the silicate backbone provides structural stability. It is notable as a potential candidate for thermal barrier coatings, refractory applications, and advanced ceramic matrix composites due to its blend of thermal and mechanical properties, though industrial adoption remains limited compared to more established ceramic systems.
