· JVASP-50926· CaSeO3

Calcium selenite (CaSeO₃) is an inorganic ceramic compound combining calcium and selenite ions, representing a specialized oxysalt ceramic with limited commercial production. While not widely deployed in mainstream engineering applications, this material is primarily of interest in research contexts for specialized optical, photochemical, and environmental remediation applications where selenium-based ceramics offer unique properties. Engineers would consider CaSeO₃ in niche roles requiring selenium incorporation into a stable ceramic matrix, particularly in laboratories investigating selenite immobilization, optoelectronic device development, or advanced ceramic composites.
