· JVASP-19596· ThAu2

ThAu₂ is an intermetallic compound composed of thorium and gold, belonging to the class of rare-earth and actinide-based metallic systems. This material is primarily of research and academic interest rather than widespread industrial use, studied for its unique crystallographic and physical properties within the thorium metallurgy family. Applications are limited to specialized research environments and theoretical materials studies, where ThAu₂ serves as a model system for understanding intermetallic bonding, phase diagrams, and the mechanical behavior of thorium-based compounds.
