· UThO3

UThO₃ is an actinide oxide ceramic compound combining uranium and thorium in a fluorite-structure oxide lattice, investigated primarily in nuclear fuel and materials research contexts. This material falls within the family of mixed-actinide oxides studied for advanced nuclear fuel formulations and high-temperature ceramic applications where superior thermal and radiation stability are required. UThO₃ is notable in nuclear science for its potential to optimize fuel density and burnup characteristics compared to conventional UO₂, though it remains largely experimental outside specialized nuclear research institutions.

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.
