· Sn0.23Te1Pb0.77

Sn₀.₂₃Te₁Pb₀.₇₇ is a lead-tin telluride alloy belonging to the IV-VI narrow bandgap semiconductor family, engineered for thermoelectric and infrared detection applications. This material is primarily used in thermoelectric power generation and cooling systems, as well as in mid-to-long wavelength infrared detectors for thermal imaging and remote sensing. The lead-telluride base provides strong phonon-scattering efficiency while the tin alloying adjusts the bandgap and carrier concentration, making this composition competitive for applications requiring high Seebeck coefficient and low thermal conductivity without the brittleness or cost disadvantages of bismuth telluride alternatives.

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.
