· JVASP-143533· U2Fe3Si5

U₂Fe₃Si₅ is an intermetallic compound combining uranium, iron, and silicon in a defined stoichiometric ratio. This is a research-phase material studied primarily for its potential in nuclear fuel applications and high-temperature structural uses, as uranium-iron silicides exhibit thermal stability and density characteristics relevant to advanced reactor designs. The material remains largely experimental; its selection would be driven by specialized nuclear engineering or materials research contexts rather than established commercial applications.

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.
