· UC2

UC2 is a uranium dicarbide ceramic compound belonging to the refractory carbide family, characterized by exceptional hardness and thermal stability at extreme temperatures. It is employed in specialized nuclear fuel applications, high-temperature structural components, and cutting tool materials where conventional ceramics fail. UC2 is valued in the nuclear and aerospace industries for its ability to withstand intense radiation, thermal cycling, and aggressive chemical environments, though its use is limited by regulatory requirements, material processing complexity, and the specialized nature of applications requiring such extreme performance.

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.
