· JVASP-90838· Cu4S3N

Cu4S3N is a copper sulfide nitride compound that combines metallic copper with sulfide and nitride phases, representing an emerging material in the family of ternary metal chalcogenide-nitrides. This composition sits at the intersection of sulfide metallurgy and nitrogen-containing ceramics, making it a candidate for research into functional or structural materials where combined properties of these phases may offer advantages. The material's applications and industrial adoption remain limited, and it should be considered primarily in experimental or development contexts where its specific phase composition and bonding characteristics address performance gaps that conventional copper alloys or sulfides cannot fill.

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.
