This work proposes a new approach for electrochemical reduction of hematite to magnetite and/or metallic iron, based on ceramic cathodes with designed microstructures. The processing method, involving emulsification of concentrated aqueous ceramic su

This work focuses on assessing the feasibility of cathodic iron extraction from the magnetite based precursors. For this, electrochemical processes at Fe3O4/alkaline electrolyte interface were screened by cycling voltammetry. Based on these results,

Alkali earth oxides are present in many ionic and mixed conductors with a potential application in solid state electrochemical or electroceramic devices. Hence, study has been made of the relative risks of carbonation of selective materials based on
