· 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.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
