· JVASP-107160· Ag3Hg

Ag₃Hg is an intermetallic compound composed of silver and mercury, belonging to the precious metal alloy family. This material is primarily encountered in dental amalgam formulations and historical scientific/laboratory applications, where its high density and metallic properties made it relevant for specialized uses. While largely superseded in modern dentistry by mercury-free alternatives due to environmental and health concerns, Ag₃Hg remains of academic and historical interest in metallurgy and materials science for understanding silver-mercury phase behavior and intermetallic structure.

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.
