UTlO3

ceramic

· UTlO3

UTlO₃ is an oxide ceramic compound containing uranium and thallium, representing an experimental or specialized material within the actinide oxide family. This material falls into the category of high-density ceramics with potential applications in nuclear fuel, radiation shielding, or advanced functional ceramics where uranium-based oxides are intentionally engineered. Engineers would consider this material primarily in nuclear science, materials research, or specialized defense applications where the combination of actinide and thallium chemistry offers unique density or radiation properties compared to 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.
