· BaCaI4

BaCaI4 is an inorganic ceramic compound composed of barium, calcium, and iodine, representing a mixed-halide perovskite-related structure in the ceramic family. This is primarily a research material investigated for optoelectronic and photonic applications rather than a conventional structural ceramic. Interest in this compound stems from its potential as a scintillator, radiation detector, or light-emitting material, with the mixed-cation approach (barium and calcium) used to tune bandgap and light-emission properties compared to single-cation iodide ceramics.
