· JVASP-37277· SmI

SmI (samarium iodide) is an ionic ceramic compound composed of samarium and iodine, belonging to the rare-earth halide family of materials. While primarily known as a laboratory reagent in synthetic organic chemistry, SmI₂ has attracted interest in materials science for potential applications in solid-state devices, photonics, and specialized ceramics due to its rare-earth composition and ionic bonding characteristics. Engineers considering SmI would typically be working in advanced research contexts rather than established industrial production, as this material remains largely experimental as a structural ceramic with potential for optical or electronic applications.

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.
