· JVASP-104550· Ac3Au

Ac3Au is an intermetallic compound composed of actinium and gold, representing a rare metal combination with potential applications in advanced materials research. This material belongs to the family of actinide-based intermetallics and remains largely experimental, with its development driven by research into high-density, corrosion-resistant metal systems and fundamental studies of f-block element chemistry. Due to actinium's radioactivity and the rarity of both constituent elements, practical engineering applications are limited to specialized research contexts rather than conventional industrial use.

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.
