· JVASP-75595· AsPAu

AsPAu is an intermetallic compound combining arsenic and gold, belonging to the family of precious metal intermetallics. This material is primarily of research and specialized industrial interest rather than a mainstream engineering choice, with potential applications in high-temperature electronics, wear-resistant coatings, and advanced semiconductor contacts where the combination of gold's chemical stability and arsenic's electronic properties may offer advantages in niche environments.
