· Na2Hg3S2.51Se1.49

Na2Hg3S2.51Se1.49 is a mixed-chalcogenide semiconductor compound containing sodium, mercury, sulfur, and selenium in a specific stoichiometry. This is a research-phase material belonging to the family of mercury-based chalcogenides, which are investigated primarily for optoelectronic and solid-state chemistry applications rather than established commercial use. The partial substitution of sulfur with selenium creates a tunable bandgap structure of interest for photovoltaic research, infrared detection, or other quantum-confined optoelectronic devices, though this specific composition remains largely in the experimental domain and is not widely deployed in production engineering.

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.
