· JVASP-64859· Ba4PbBr

Ba₄PbBr is an inorganic ceramic compound belonging to the halide perovskite family, combining alkaline earth (barium), post-transition (lead), and halide (bromine) elements. This material is primarily of research interest for optoelectronic and photovoltaic applications, where lead halide perovskites have shown promise for light emission, detection, and energy conversion due to tunable bandgaps and solution-processability. Engineers would consider this compound in next-generation solar cells, light-emitting devices, or radiation detectors where the lead–bromine framework offers improved stability or performance characteristics compared to purely organic–inorganic hybrids, though commercial deployment remains limited pending further development and toxicity mitigation strategies.

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.
