· JVASP-113641· Hg2I

Hg₂I is an inorganic ceramic compound in the mercury halide family, composed of mercury and iodine. This material is primarily of research and specialized instrumentation interest rather than mainstream industrial use, with applications in radiation detection and optoelectronic devices where its high atomic number and density provide sensitivity to high-energy photons. Its use is limited by toxicity concerns and regulatory restrictions on mercury-containing materials, making it relevant only in niche applications where alternatives cannot match its performance characteristics.

Regulatory Screening

Environmental

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.
