GaAu3
metal· JVASP-126889· GaAu3
GaAu3 is an intermetallic compound composed of gallium and gold, belonging to the family of precious metal intermetallics. This material is primarily of research and specialized industrial interest rather than a commodity engineering material, with applications centered on semiconductor contacts, microelectronics, and high-reliability interconnect systems where the combination of gold's conductivity and chemical stability with gallium's semiconducting properties enables unique functionality. Its use is driven by specific requirements in space electronics, military systems, and advanced optoelectronic devices where performance and reliability justify the high material cost.
