· Pr43Au157

Pr43Au157 is an intermetallic compound composed of praseodymium and gold, representing a rare-earth–noble-metal system studied primarily in materials research rather than established industrial production. This material belongs to the family of intermetallic compounds, which are ordered crystalline phases with specific stoichiometry that can exhibit unique combinations of hardness, thermal stability, and electronic properties. The Pr-Au system is investigated for potential applications in high-temperature structural materials, catalysis, and electronic devices, though commercial deployment remains limited; researchers are drawn to rare-earth–gold compounds for their potential to achieve property combinations unattainable in conventional alloys, particularly at elevated temperatures or in demanding chemical environments.
