· Si4 U2

Si₄U₂ is an experimental intermetallic compound combining silicon and uranium, representing a specialized research material within the uranium-silicon phase diagram rather than a commercially established alloy. This compound belongs to the family of refractory intermetallics and is primarily of interest in nuclear materials science and advanced ceramics research, where its thermal stability and potential for high-temperature applications are being investigated. The material remains largely confined to laboratory and fundamental research contexts, with limited industrial deployment compared to conventional nuclear fuels or structural alloys.

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.
