· Cd2As3I

Cd2As3I is a cadmium arsenide iodide ceramic compound belonging to the family of mixed-metal chalcogenides and pnictogens. This is a research-stage material investigated for optoelectronic and semiconductor applications rather than a mature commercial ceramic. The compound's potential lies in photovoltaic devices, infrared detectors, and nonlinear optical applications where the bandgap and crystal structure of cadmium-arsenic-iodine systems offer tunable electronic properties; however, toxicity concerns associated with cadmium and cadmium compounds severely limit industrial adoption and restrict use primarily to controlled laboratory environments.
