· JVASP-118010· Cd2O

Cadmium oxide (Cd2O) is a ceramic compound combining cadmium and oxygen, belonging to the metal oxide ceramic family. Historically used in applications requiring electrical conductivity combined with ceramic stability—notably in resistor manufacturing, photovoltaic devices, and specialized coatings—though its use has declined significantly due to cadmium's toxicity and strict environmental regulations in most developed markets. Modern interest in Cd2O is primarily in research contexts exploring transparent conducting oxides and thin-film semiconductors, where its optical and electrical properties offer potential for optoelectronic devices, though bismuth oxide, tin oxide, and indium tin oxide (ITO) are now the preferred industrial alternatives.

Regulatory Screening

Environmental

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
