· Cu18S11

Cu18S11 is a copper-sulfur compound that belongs to the family of copper sulfides, likely representing a specific stoichiometric or near-stoichiometric phase in the Cu-S binary system. This material is of primary interest in materials research and solid-state chemistry rather than established industrial production, with potential applications emerging in semiconductor physics, electrochemistry, and thermal energy storage where copper sulfides show promise due to their mixed-valence copper character and variable electronic properties.

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.
