ceramic

· JVASP-50388· Sm4U2O11

Sm₄U₂O₁₁ is a samarium-uranium mixed oxide ceramic compound, representing a complex ternary oxide system that combines rare-earth (samarium) and actinide (uranium) elements. This material is primarily of research and specialized nuclear/materials science interest rather than widespread industrial use, investigated for potential applications in nuclear fuel chemistry, actinide immobilization, and high-temperature ceramic systems where mixed-valence oxides may offer unique thermal or chemical properties.

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.
