· Hg2I2

Hg₂I₂ (mercury(I) iodide) is an ionic semiconductor compound belonging to the mercury halide family, characterized by a layered crystal structure with mixed-valence mercury cations. This material is primarily investigated in research contexts for radiation detection and X-ray/gamma-ray spectroscopy applications, where its high atomic number and bandgap properties offer potential advantages over conventional semiconductors, though it remains largely experimental with limited commercial deployment due to stability and purification challenges.

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.
