· JVASP-16158· USiAu

USiAu is an intermetallic compound combining uranium, silicon, and gold, representing a specialized metal system of primary interest to researchers rather than established commercial applications. While not widely deployed in conventional engineering, this material belongs to the family of uranium-based intermetallics, which are explored for nuclear fuel applications, radiation shielding, and specialized high-density components where uranium's properties are advantageous. The gold addition may enhance corrosion resistance or modify phase stability compared to binary uranium-silicon systems, though detailed performance data and processing routes for this specific ternary composition remain limited to research contexts.

Export Control

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.
