· CdSeO3

Cadmium selenite (CdSeO₃) is an inorganic ceramic compound combining cadmium, selenium, and oxygen. While not a widely commercialized engineering material, it belongs to the family of metal selenite ceramics that have attracted research interest for optical, electronic, and photovoltaic applications due to the semiconductor properties of cadmium selenide-related systems. The material remains largely in the experimental phase, with potential relevance in niche optoelectronic and radiation detection contexts where selenite-based ceramics can offer unique band-gap and scintillation characteristics, though availability, toxicity concerns associated with cadmium, and competing materials limit mainstream engineering adoption.
