· F22 Au2 Th4

F22 Au2 Th4 is an intermetallic compound combining gold and thorium in a defined stoichiometric ratio, belonging to the class of rare-earth and precious-metal intermetallics. This material exists primarily in the research domain rather than widespread industrial production, with potential applications in high-temperature structural uses, electronic devices, or specialized coating systems where the unique combination of gold's chemical stability and thorium's nuclear properties may be relevant. The material represents an exploratory composition within the Au-Th binary system, and its practical adoption would depend on demonstrating cost-effectiveness and performance advantages over conventional alternatives in specific high-value applications.
