· JVASP-123787· Bi5Br

Bi₅Br is an inorganic ceramic compound in the bismuth halide family, composed of bismuth and bromine. This material is primarily of research interest for optoelectronic and solid-state applications, particularly in lead-free perovskite-related systems and semiconductor device development. While not yet widely deployed in high-volume industrial production, bismuth halides are being investigated as safer alternatives to lead-based semiconductors, with potential applications in photovoltaics, X-ray detection, and radiation sensing due to their electronic and structural properties.

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.
