ceramic· JVASP-29551· Hg3AsSe4Br
Hg3AsSe4Br is a mixed-halide chalcogenide ceramic compound containing mercury, arsenic, selenium, and bromine—a rare quaternary composition that belongs to the family of heavy-metal chalcohalides. This material is primarily of research and experimental interest rather than established in mainstream production, with potential applications in nonlinear optics, infrared photonics, and solid-state radiation detection where its unique crystal structure and electronic properties may offer advantages over more common alternatives.

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.
