· O8 Na4 Fe2

O8 Na4 Fe2 is an iron-sodium oxide compound classified as a semiconductor, representing a mixed-valence iron oxide system with potential electrochemical activity. This material belongs to the family of layered oxide frameworks and is primarily of research interest rather than established industrial production; it is being investigated for energy storage applications, particularly in battery and supercapacitor systems where its mixed oxidation states and sodium content could enable ion transport and electron conduction. The combination of iron and sodium oxides makes it a candidate for next-generation sodium-ion battery cathodes and related electrochemical devices seeking alternatives to lithium-based systems.

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.
