· JVASP-123650· CaSe2

Calcium diselenide (CaSe₂) is an inorganic ceramic compound belonging to the alkaline-earth chalcogenide family, characterized by ionic bonding between calcium and selenium atoms. While not widely commercialized, CaSe₂ and related calcium chalcogenides are of research interest for optoelectronic and photonic applications, particularly in infrared spectroscopy windows and as potential semiconductor materials where its wide bandgap and thermal stability offer advantages over more common oxides in specialized environments.

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.
