Summary

Plates and rods of NiO-CSZ (cubic stabilised zirconia) and CoO-CSZ eutectics were prepared using the Laser Zone Melting technique. This highly textured material consists of alternating lamellae of the transition metal oxide and zirconia with a thickness ranging from 0.2 to 4 μm. The controlled reduction leads to a material consisting of porous metallic layers packed in between the CSZ skeleton. The material is a porous mixed ionic and electronic conductor and its thermal expansion coefficients are those of the cubic zirconia. Using the Pulse Injection Metal Organic Chemical Vapor Deposition technique (PIMOCVD) we have deposited a thin and tight layer of few microns of CSZ on top of this structured cermet. This new material has been characterised on the light of its possible application as an anode + membrane component for IT-SOFC.
