Electrochemical Behaviour of Lamellar Interfaces in CoO - ZrO2(CaO) Aligned Eutectic Structures Submitted to Chemical Reduction
Published online by Cambridge University Press: 28 February 2011
Abstract
In a previous study we have examined the reduction of nickel oxide into nickel in NiO-ZrO2(CaO) aligned lamellar eutectic structures [1-2]. From the data which were obtained, we developed a model accounting for the fast reduction of nickel oxide; in particular it was shown that reduction takes place through the action of an electrochemical local cell, involving fast transport of oxygen to the sample surface through the cubic zirconia phase [2].
