K2SeBr6 is an inorganic halide perovskite ceramic compound containing potassium, selenium, and bromine. This material belongs to the family of mixed-halide perovskites and related ionic ceramics, which are primarily of research interest rather than established industrial use. Perovskite halides and related compounds are investigated for optoelectronic applications including photovoltaics, scintillators, and radiation detectors due to their tunable bandgaps and high absorption coefficients, though K2SeBr6 specifically remains in the developmental stage with limited commercial deployment compared to more widely studied perovskite variants.
