· Na4 O2

Na₄O₂ is a sodium oxide compound classified as a semiconductor, representing an experimental material within the alkali metal oxide family. This compound is primarily of research interest rather than established in commercial production, with potential applications in solid-state ionics and energy storage systems where sodium-based ceramics are being explored as alternatives to lithium compounds. The material's semiconducting properties and sodium composition make it relevant to emerging technologies in battery electrolytes, oxygen sensors, and fast-ion conducting ceramics, though its practical engineering implementation remains limited compared to more established sodium oxide phases.

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.
