Pb4 O4
semiconductor· Pb4 O4
Pb₄O₄ is a mixed-valence lead oxide semiconductor, a rare mixed oxidation state compound within the lead oxide family that bridges properties between PbO (litharge) and PbO₂. This material remains primarily of research interest for fundamental materials science studies rather than established industrial production; it is investigated for potential applications in advanced ceramics, photocatalysis, and solid-state electronics where its unique electronic structure and intermediate oxidation states may offer distinct advantages over conventional lead oxides.

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.
