· Pb1 S1

Lead sulfide (PbS), commonly known as galena, is a IV-VI semiconductor compound with a rock-salt crystal structure. It is primarily used in infrared detection and thermal imaging applications, where its narrow bandgap and high carrier mobility make it valuable for room-temperature and cooled detector systems. PbS is also employed in solar cells and photodetectors, offering advantages over wider-bandgap alternatives in capturing longer-wavelength infrared radiation, though it faces competition from more thermally stable compounds in demanding aerospace and military applications.

Export Control

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.
