· JVASP-146384· U6Si11O

U6Si11O is a uranium silicate ceramic compound combining uranium, silicon, and oxygen in a mixed-valence structure. This material belongs to the family of actinide silicates and is primarily of research and development interest rather than established industrial production. Uranium silicate ceramics are investigated for nuclear fuel applications, immobilization of radioactive waste, and high-temperature structural applications where their chemical stability and thermal properties offer potential advantages over conventional ceramics.

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.
