· Ta3Au2

Ta3Au2 is an intermetallic compound composed of tantalum and gold, representing a rare combination of a refractory metal with a precious metal. This material exists primarily in materials research and experimental contexts rather than widespread industrial production, with potential applications leveraging tantalum's high melting point and chemical resistance alongside gold's corrosion immunity and electrical properties.
