Cu4O3
ceramic· JVASP-57653· Cu4O3
Cu₄O₃ is a mixed-valence copper oxide ceramic compound that exists in a narrow compositional window between cuprite (Cu₂O) and tenorite (CuO). This material is primarily of academic and research interest rather than established industrial use, as it exhibits complex crystal chemistry and oxygen-deficient properties that make it challenging to synthesize and stabilize. Potential applications are being explored in solid-state electronics, catalysis, and energy storage systems where its intermediate oxidation state and mixed-metal oxide properties could offer advantages over conventional binary copper oxides, though it remains largely in the experimental phase without widespread commercial adoption.

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.
