· Sn0.25Te1Pb0.75

Sn0.25Te1Pb0.75 is a ternary lead-tin telluride alloy belonging to the IV-VI narrow-bandgap semiconductor family, engineered for thermoelectric and infrared detection applications. This material combines lead telluride's thermal power generation capabilities with tin telluride contributions, optimized for mid-to-long wavelength infrared sensing and waste heat recovery systems operating in the intermediate temperature range. The tin doping modifies the electronic band structure and carrier concentration relative to pure PbTe, making it attractive for tuning device performance in thermal imaging, night-vision systems, and thermoelectric generators without requiring complex multi-stage cooling.

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.
