· PmHgAu2

PmHgAu2 is an intermetallic compound composed of promethium, mercury, and gold, representing a specialized alloy in the precious metal and rare earth chemistry space. This is primarily a research material rather than an established commercial alloy; it belongs to the family of ternary intermetallics that are studied for their unique electronic, magnetic, or catalytic properties arising from the combination of a radioactive rare earth element (promethium), a liquid metal (mercury), and a noble metal (gold). Engineers would encounter this material only in specialized contexts such as fundamental materials research, nuclear science applications, or advanced catalysis development where the specific properties conferred by this particular elemental combination are required.

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.
