Ac3Au
metal· 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.
