· Na0.02Pb0.98Te0.75Se0.25

Na0.02Pb0.98Te0.75Se0.25 is a sodium-doped lead telluride-selenide solid solution, a narrow-bandgap semiconductor compound belonging to the IV-VI family of thermoelectric materials. This is a research-grade composition designed for thermoelectric energy conversion applications, where the sodium dopant and selenium alloying are tuned to optimize charge carrier concentration and phonon scattering for improved efficiency. The material is primarily investigated for waste heat recovery and power generation in advanced thermal management systems, particularly where low operating temperatures and efficient conversion of small temperature gradients are required.

Regulatory Screening

Environmental

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.
