Ca2AsI is an inorganic ceramic compound combining calcium, arsenic, and iodine elements. This is a research-phase material studied primarily for its potential in optoelectronic and photonic applications, particularly in the halide perovskite family where mixed-cation compositions are explored for tunable bandgap and light-absorption properties. Ca2AsI represents an experimental candidate for next-generation semiconducting ceramics where arsenic and iodine components may enable unique electronic behavior, though industrial adoption remains limited and the material's stability and scalability require further development.
