· CdSb

CdSb is a binary III-V semiconductor compound composed of cadmium and antimony, belonging to the family of narrow-bandgap semiconductors used primarily in infrared and photonic applications. Historically employed in infrared detectors, thermal imaging sensors, and photodiodes operating in the mid-to-far infrared spectrum, CdSb offers sensitivity in wavelength ranges where competing materials become ineffective. While largely superseded in mainstream commercial applications by alternatives such as HgCdTe and modern quantum-dot systems due to cadmium toxicity concerns and processing challenges, CdSb remains relevant in specialized research contexts and legacy defense/aerospace systems requiring robust, cost-effective infrared detection at specific wavelengths.

Export Control

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.
