· JVASP-76711· Na2HgAu

Na2HgAu is an intermetallic compound combining sodium, mercury, and gold in a fixed stoichiometric ratio. This is an experimental or specialized research material rather than a conventional engineering alloy; compounds in this family are primarily studied for fundamental materials science, thermodynamic properties, or potential electrochemical applications. Such ternary intermetallics are rarely deployed in production engineering due to processing complexity, cost, toxicity concerns (mercury), and limited property advantages over established alternatives.
