· JVASP-12141· BaB2Se6

BaB₂Se₆ is a barium boron selenide ceramic compound belonging to the family of layered metal chalcogenides. This is primarily a research material being investigated for its layered crystal structure and potential optoelectronic properties, rather than an established commercial ceramic. The material's interest stems from its potential applications in semiconducting devices, nonlinear optics, and photodetection, where its layered nature and selenium content could enable tunable electronic or optical behavior compared to conventional oxides or nitrides.
