Used in the preparation of cadmium oxide coatings and thin films through chemical bath deposition and spray pyrolysis techniques, particularly in the fabrication of semiconductor layers for solar cells and photovoltaic devices. Employed as a catalyst precursor in certain organic reactions and in the synthesis of cadmium-based nanomaterials. Also utilized in electroplating baths to deposit cadmium metal coatings for corrosion protection in aerospace and automotive parts, although this use is limited due to environmental and toxicity concerns. Serves as a source of cadmium ions in laboratory research and analytical standards, mainly in studies related to metal toxicity and environmental monitoring, as well as in the preparation of other cadmium compounds including red and yellow pigments for glass and ceramics.
