· Nb4 W2 O16

Nb₄W₂O₁₆ is a mixed-metal oxide semiconductor composed of niobium and tungsten in a layered perovskite-related structure. This compound belongs to the family of transition-metal oxides studied for photoelectric and electrochemical applications, where the combination of two d-block metals creates favorable band-gap properties and catalytic activity. While primarily a research material rather than a commodity engineering material, Nb₄W₂O₁₆ shows promise in photocatalysis and ion-transport applications where the synergistic effects of niobium and tungsten oxides can be exploited.

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.
