· JVASP-133605· KNa2FeO3

KNa2FeO3 is a mixed-alkali iron oxide ceramic compound that belongs to the family of complex metal oxides with potential electrochemical and structural applications. This material is primarily of research interest rather than established industrial production, explored for its ion-conducting properties and stability in oxidizing environments, making it a candidate for solid-state electrolytes, oxygen separation membranes, and advanced catalytic supports where mixed-valence iron oxides offer advantages over single-cation alternatives.

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.
