CdCl2
ceramic· CdCl2
Cadmium chloride (CdCl2) is an inorganic ceramic compound that exists as a white crystalline solid at room temperature. Historically used in electroplating, photoelectric devices, and as a precursor in cadmium-based semiconductor manufacturing, CdCl2 has seen declining industrial adoption due to cadmium's toxicity and regulatory restrictions in many jurisdictions. Contemporary research interest focuses on CdCl2 as a thin-film material for photovoltaic applications, particularly as an interface layer in cadmium telluride (CdTe) solar cells, where its layered crystal structure and tunability make it relevant to next-generation energy conversion systems.

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.
