· LaAu

LaAu is an intermetallic compound combining lanthanum and gold, belonging to the rare-earth metal alloy family. This material is primarily of research and specialized industrial interest, investigated for applications requiring the unique combination of rare-earth reactivity and gold's chemical inertness and high density. LaAu and related lanthanum-gold systems are studied for potential use in catalysis, electronic devices, and high-temperature applications where rare-earth intermetallics offer thermal stability and specific electronic properties unavailable in conventional alloys.

Export Control

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.
