· JVASP-29407· Hg3AsS4Br

Hg₃AsS₄Br is a mixed-halide mercury arsenic sulfide compound belonging to the heavy-metal chalcogenide ceramic family. This is a specialized research material rather than an established commercial ceramic, primarily investigated for its semiconducting and photosensitive properties in optical and radiation detection applications. The compound's notable combination of heavy elements and mixed anionic character makes it of interest for niche optoelectronic research where alternatives like conventional arsenides or sulfides prove insufficient.

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.
