U3 O5

semiconductor

· U3 O5

U₃O₅ is a mixed-valence uranium oxide semiconductor belonging to the family of reduced uranium oxides, positioned between UO₂ and U₄O₉ in the uranium oxide phase diagram. This material is primarily of research and developmental interest rather than established industrial production, with potential applications in nuclear fuel cycles, solid-state electronics, and advanced ceramic systems where its semiconducting properties and thermal stability at high temperatures could provide advantages over conventional oxides.

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.
