· Hg6 Cl4 O4

Hg₆Cl₄O₄ is an inorganic semiconductor compound containing mercury, chlorine, and oxygen—a mixed-valence mercury halide oxide that belongs to the family of layered mercury compounds. This material is primarily of research interest rather than established industrial production, investigated for potential optoelectronic and photocatalytic applications due to its semiconducting behavior and crystal structure. Engineers and researchers explore such mercury-based compounds for specialized photonic devices, though environmental and toxicity concerns around mercury limit practical commercialization compared to lead-free semiconductor alternatives.

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.
