SrSe2

Strontium diselenide (SrSe₂) is an inorganic ceramic compound belonging to the metal selenide family, characterized by ionic bonding between strontium cations and selenide anions. While primarily a research and specialized material, SrSe₂ is investigated for optoelectronic and photovoltaic applications where wide-bandgap semiconductors are needed, as well as in thermal and radiation-resistant ceramic systems. The material remains largely experimental; engineers would consider it for niche applications requiring selenide-based ceramics in high-temperature or radiation environments where conventional oxides are unsuitable, though availability and cost typically limit adoption to laboratory and prototype development.
