Preparation and characterization of highly densified YBa₂Cu₃O_7‐δ Ceramics used for electrochemical oxidation

Abstract

An appropriate treatment called “Vacuum‐Oxygen Cycle” (V.O.C.) has been carried out in order to obtain highly densified YBa2Cu3O7‐δceramics. The obtained materials exhibit a homogeneous oxygen distribution and their feature have been characterized using relevant physical measurements. Preliminary electrochemical experiments have been performed and this treatment seems to improve their superconducting properties.
