CaGa2As2
ceramic· JVASP-63137· CaGa2As2
CaGa2As2 is a ternary ceramic compound belonging to the family of III-V semiconductors and chalcopyrite-like structures, combining calcium with gallium and arsenic elements. This material is primarily of research interest for optoelectronic and photonic device applications, where its bandgap and crystal structure offer potential advantages in ultraviolet to infrared light emission and detection. While not yet widely commercialized compared to binary GaAs or other established semiconductors, compounds in this family are explored for specialized applications requiring tunable electronic properties or enhanced performance in high-energy photon 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.
