· JVASP-14038· Hg2IO

Hg2IO is a mixed-valence mercury iodide oxide ceramic compound combining mercury, iodine, and oxygen in its crystal structure. This material belongs to the family of heavy-metal halide ceramics and appears primarily in research contexts rather than established industrial production, where it is investigated for potential applications in radiation detection, photonic materials, and specialized optical systems that exploit the strong X-ray absorption and electronic properties characteristic of mercury-containing compounds.

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.
