· Sr2CaI6

Sr2CaI6 is an inorganic ceramic compound belonging to the halide perovskite family, specifically a mixed-cation iodide with strontium and calcium. This is a research-phase material primarily investigated for optoelectronic and photovoltaic applications due to its potential bandgap tunability and ionic conductivity, rather than as a conventional structural ceramic. Sr2CaI6 represents a promising class of lead-free halide perovskites being developed as alternatives to conventional perovskite semiconductors for next-generation solar cells, scintillators, and radiation detectors, where stability and environmental benignity are critical design drivers.
