Si3Au10
metal· JVASP-144653· Si3Au10
Si3Au10 is an intermetallic compound combining silicon and gold, belonging to the class of metallic intermetallics that exhibit ordered crystal structures and properties distinct from their constituent elements. This material is primarily of research and specialized industrial interest, used in high-reliability electronic applications where the chemical stability and thermal properties of gold-silicon systems provide advantages in bonding, contact, and barrier layer applications. The compound's notable density and intermetallic character make it relevant to scenarios requiring resistance to corrosion, thermal cycling, and electrical degradation in miniaturized or high-precision assemblies.
