La2Au

La₂Au is an intermetallic compound combining lanthanum (a rare earth element) with gold, forming an ordered metallic phase. This material is primarily of research interest rather than established in high-volume production, studied for its potential in advanced applications requiring the unique properties arising from rare earth–noble metal combinations. Potential applications leverage the chemical activity of lanthanum paired with gold's thermal stability and corrosion resistance, with investigation focused on catalysis, hydrogen storage materials, and specialized electronic or photonic devices where rare earth intermetallics show promise.
