Th3Au
metal· JVASP-37375· Th3Au
Th3Au is an intermetallic compound in the thorium-gold system, representing a research-phase material combining a radioactive actinide metal with a noble metal. While not yet established in mainstream industrial production, thorium-gold intermetallics are studied primarily in materials science for their potential high-temperature stability and unique mechanical properties; however, their practical adoption is severely limited by thorium's radioactivity, regulatory complexity, and the high cost of gold, making them relevant only for specialized research applications rather than conventional engineering designs.

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.
