· JVASP-90875· Tl3Au

Tl₃Au is an intermetallic compound combining thallium and gold in a fixed 3:1 stoichiometric ratio, belonging to the class of precious metal intermetallics. This material is primarily of research and academic interest rather than established industrial use, studied for its unique electronic and structural properties within the broader family of gold-based intermetallic compounds. Engineers and materials scientists investigate Tl₃Au in specialized applications where the combination of thallium and gold's properties—such as unusual electrical characteristics or phase behavior—may offer advantages in niche electronic or high-temperature material systems, though practical adoption remains limited due to cost, toxicity considerations of thallium, and competing alternatives.

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.
