ceramic

· HgIBr

HgIBr is a mixed-halide perovskite ceramic compound containing mercury, iodine, and bromine. This material belongs to the family of halide perovskites, which are primarily investigated as research compounds rather than established industrial materials, with potential applications in optoelectronic and photonic devices due to their tunable bandgap and crystalline structure.

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.
