· Na1 Br1

Sodium bromide (NaBr) is an ionic halide ceramic compound with a rock salt crystal structure, notable for its optical transparency in the infrared spectrum and moderate mechanical stiffness. This material finds application primarily in infrared optics and spectroscopy systems where its transmission characteristics and relative chemical stability are advantageous compared to other halide ceramics. Engineers select NaBr for specialized optical windows and lenses in thermal imaging and laboratory instrumentation, though its hygroscopic nature and solubility in water limit its use in humid or aqueous environments.

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.
