· Bi4 As4 O16

Bi₄As₄O₁₆ is a bismuth arsenate compound belonging to the family of metal oxyarsenates, classified as a semiconductor material with a layered or framework crystal structure. This is primarily a research-phase compound studied for its electronic and optical properties rather than an established commercial material. The bismuth arsenate family shows promise in optoelectronic applications, photocatalysis, and solid-state physics due to bismuth's strong spin-orbit coupling and the tunable bandgap characteristics common in mixed-metal oxyanion compounds, though industrial adoption remains limited compared to more mature semiconductor systems.

Quality & Standards

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.
