· Te0.5Pb1Se0.5

Te₀.₅Pb₁Se₀.₅ is a ternary lead chalcogenide semiconductor compound combining tellurium, lead, and selenium in a 1:2:1 ratio. This material belongs to the IV-VI narrow-bandgap semiconductor family and is primarily investigated as a thermoelectric material, with potential applications in mid-range temperature thermal energy conversion and infrared detector systems. Lead chalcogenides like this composition are valued for their tunable bandgap and strong thermoelectric performance, making them alternatives to lead telluride (PbTe) and lead selenide (PbSe) for heat-to-electricity conversion in industrial waste heat recovery and space power systems.

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.
