· Ag2 I4 Hg1

Ag₂I₄Hg₁ is a mixed-halide semiconductor compound containing silver, iodine, and mercury—a specialized material from the family of halide semiconductors used primarily in research contexts. This compound is investigated for optoelectronic and photosensitive applications where the combination of heavy metals and halides produces unique electronic band structures; however, it remains largely experimental and is not widely deployed in mainstream industrial products. Engineers considering this material should be aware it represents an early-stage research compound with potential relevance to niche photovoltaic or radiation detection systems, though mercury content and environmental concerns limit commercial adoption compared to lead-free or more stable halide 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.
