· Ag2 Hg2 O4

Silver mercury oxide (Ag₂Hg₂O₄) is a mixed-valence semiconductor compound combining silver and mercury oxides, representing a rare intermetallic oxide system of primarily academic and experimental interest. While not widely deployed in mainstream engineering, compounds in the silver–mercury–oxygen family have been investigated for electrochemical energy storage, sensing applications, and solid-state electronic devices, though toxicity concerns associated with mercury limit practical industrial adoption compared to safer alternative semiconductor materials.

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.
