Abstract
Thin ceramic buffer layers of CeO2 and La2Zr2O7 were produced by a sol-gel process based on metal acetates, organic complexing agents and water. Thermal analysis and thermomicroscopy have learnt us something about the chemical characteristics of the precursor solution. Single or multiple layers of the ceramic buffer layer were deposited on Ni-5at%W textured tape using the dip-coating technique. The desired (001) orientation was obtained after a high temperature (1050°C) heat treatment under forming gas (Ar-5%H2). It was shown that changing the thickness of the layers from 10 nm to 100 nm by controlling the dip-coating parameters, plays a crucial role in obtaining the (00l) texture. In manufacturing high quality buffer layers for coated conductors, it is of major importance to create a strong texture throughout the layer. By means of XRD and pole figures, the bulk orientation was studied. Special attention was given to the texture of the top layer using RHEED. The microstructure of the films was further studied by SEM, AFM, FIB and HRTEM.
