CoHgO2S
ceramic· CoHgO2S
CoHgO2S is a ternary ceramic compound containing cobalt, mercury, oxygen, and sulfur—a mixed-valence oxysulfide that belongs to the family of transition metal chalcogenides. This is an experimental or specialized research material rather than a commodity ceramic, investigated primarily for its potential electronic and photocatalytic properties in the context of sulfide-based semiconductors and functional oxides. Its use in industry remains limited; primary interest lies in materials research for photocatalysis, environmental remediation, or solid-state chemistry applications where the combination of mercury, cobalt, and chalcogenide chemistry offers tunable band gaps or unique defect chemistry.

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.
