· Nb2 Se28 W12

Nb₂Se₂₈W₁₂ is a complex mixed-metal chalcogenide compound combining niobium, selenium, and tungsten—a research-phase material rather than a production alloy. This composition falls within the family of polymetallic selenides, which are primarily investigated for semiconductor, thermoelectric, and electrochemical applications where transition metal chalcogenides show promise for energy conversion and storage. The material's notable advantage over simpler binary selenides lies in its potential for tuned electronic properties and enhanced catalytic activity through compositional complexity, though industrial adoption remains limited pending characterization of thermal stability, scalability, and cost-benefit validation.

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.
