· Pb0.85Ge0.15Te

Pb0.85Ge0.15Te is a lead-germanium telluride alloy belonging to the IV-VI narrow-bandgap semiconductor family, engineered to optimize the thermoelectric properties of lead telluride through partial germanium substitution. This material is primarily investigated for thermoelectric energy conversion applications where waste heat recovery and solid-state cooling are critical, offering improved figure-of-merit and thermal stability compared to pure PbTe, particularly in intermediate-temperature operating ranges (300–600 K). The germanium alloying reduces lattice thermal conductivity while maintaining electronic transport properties, making it attractive for power generation and refrigeration systems where conventional mechanical approaches are impractical or inefficient.

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.
