· JVASP-15167· USeO

USeO is a uranium-selenium-oxide ceramic compound that exists primarily in academic and research contexts rather than as an established commercial material. This material represents a family of heavy-metal oxide ceramics studied for its potential in nuclear materials science, actinide chemistry, and high-density ceramic applications. While not widely deployed in industry, uranium-bearing oxides like this are of interest for specialized nuclear fuel forms, waste immobilization matrices, and fundamental materials research where high density and chemical stability are requirements.

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.
