ceramic

· JVASP-123508· U3O

U3O is a uranium oxide ceramic compound representing an intermediate oxidation state in the uranium-oxygen system, distinct from the more common UO2 (uranium dioxide) and U3O8. This material is primarily of research and specialized nuclear fuel interest, studied for its potential role in advanced nuclear fuel formulations and fundamental materials science investigations of uranium oxidation chemistry. Its notable characteristics within the uranium oxide family make it relevant for nuclear engineers and materials scientists exploring fuel behavior under specific thermal and chemical conditions, though it remains less commercially prevalent than conventional uranium dioxide fuels.

Regulatory Screening

Environmental

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.
