· JVASP-35799· ThAu

ThAu is an intermetallic compound composed of thorium and gold, belonging to the rare-earth and precious-metal alloy family. This material exists primarily in research and specialized applications due to the high cost and scarcity of both constituent elements, with potential interest in high-temperature structural applications and electronics where thermal stability and specific density characteristics are valued. Engineers would consider ThAu only in niche contexts where the unique combination of thorium's nuclear properties and gold's corrosion resistance justifies the material and processing costs.
