ceramic

· Ni3O4

Ni3O4 is a mixed-valence nickel oxide ceramic compound combining nickel in both +2 and +3 oxidation states, belonging to the spinel-related oxide family. It appears primarily in battery and catalysis research, where it is investigated as an electrode material for rechargeable batteries (particularly lithium-ion and supercapacitor applications) and as a catalyst precursor for electrochemical and thermal processes. Engineers would consider this material for energy storage systems where the redox activity of nickel oxides can be leveraged, and in catalytic applications where structural stability and surface chemistry are critical—though it remains largely in development rather than high-volume industrial use.

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.
