· JVASP-92545· TmAu4

TmAu4 is an intermetallic compound combining thulium (a rare earth element) with gold in a 1:4 stoichiometric ratio. This material belongs to the rare earth–noble metal intermetallic family and is primarily of research interest rather than established in high-volume industrial production. TmAu4 is investigated for potential applications in thermoelectric devices, magnetic materials, and advanced electronic systems where the combination of rare earth magnetic properties and gold's chemical stability might provide unique functional characteristics.

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.
