· Na1 I1

Sodium iodide (NaI) is an inorganic ionic compound and semiconductor material that belongs to the halide family, commonly found in its crystalline form. While primarily known for scintillation detection and radiation sensing applications, NaI exhibits semiconducting properties under specific conditions and is studied for optoelectronic and photonic devices. This material is notable for its transparency to visible and near-infrared light combined with its ionic bonding characteristics, making it relevant for specialized sensing and detection systems where alternatives like silicon semiconductors are unsuitable.

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.
