Correlations Composition - Processing - Microstructure - Properties for Ceria - Based Solid Electrolytes

Abstract:

The main objective of this work is to study the correlation between composition, microstructure, processing and properties of doped ceria. Doped ceria with heterovalent cations can be used as solid electrolyte for solid oxide fuel cells working at intermediate temperatures (SOFC-IT). This study is made in order to obtain information, which can be useful for further improvement of this type of materials. Multivariate analysis techniques, such as Principal Component Analysis (PCA) and Self-Organizing Maps (SOMs) were used on a database consisting of 18 samples which differ by composition and by processing methods. Experimental data regarding these samples consisted in information about composition, SEM images and the property of choice, the electrical conductivity. SEM images were digitally processed to isolate grain boundaries; on the 18 resulting images it was computed the Fractal Dimension, as a parameter containing both information about size and shape of the grains, therefore characterising the microstructure. All results were, then, subjected to Multivariate analysis taking into account, also, the processing methods. The aim is to extract useful information from the available experimental data. Results encourage us to assume that even identification and diagnose can become possible based on the present work, given an adequate database. The overall procedure can be applied to any crystalline material.
