· Ta1 Pb1 Se2

Ta₁Pb₁Se₂ is a ternary semiconductor compound combining tantalum, lead, and selenium elements, representing an understudied composition within the broader family of metal chalcogenides. This material belongs to the class of mixed-metal selenides and is primarily of interest in solid-state physics and materials research rather than established industrial production; it may be explored for thermoelectric applications, photovoltaic absorbers, or other electronic devices where the layered or band-structure properties of lead-containing selenides could be leveraged.

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.
