· JVASP-139578· NaI2

Sodium iodide (NaI₂) is an inorganic ionic ceramic compound formed from sodium and iodine elements. This material is primarily encountered in research and specialized industrial contexts rather than as a structural ceramic, with applications centered on its optical and radiation-detection properties. NaI₂ belongs to the halide ceramic family and is notable for its potential in scintillation detection and photonic materials, though it is less commonly deployed than its cousin sodium iodide (NaI), which dominates the scintillation detector market.

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.
