· Pb0.83Sn0.17Te

Pb0.83Sn0.17Te is a lead-tin telluride alloy, a narrow-bandgap semiconductor compound belonging to the IV-VI semiconductor family commonly used in infrared optoelectronic devices. This material is primarily employed in thermoelectric cooling modules and infrared detectors operating in the mid-infrared wavelength range, where its tunable bandgap and strong thermoelectric properties make it valuable for cryogenic and thermal management applications. The lead-tin composition offers improved performance compared to pure lead telluride in specific temperature ranges and detector sensitivity windows, making it a preferred choice for military, aerospace, and scientific instrumentation where reliable thermal or infrared sensing is critical.

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.
