Abstract

The analyses of ceramic interfaces of oxides will be performed by the electrochemical impedance spectroscopy technique over wide frequency (5 Hz - 110 MHz), temperature (78 K - 1600 K), and partial pressure of oxygen (10 ppm - 1 atm) ranges. Several ceramic oxides, synthesized through chemical techniques, to be sintered under different experimental procedures, have been chosen due to their importance for the development of electroceramic devices. The analysis of pre-sintered powders will be performed by helium picnometry, gas adsorption (BET), X-ray diffraction (XRD) , and Fourier Transform Infrared Spectroscopy (FTIR) for physical and chemical evaluation of the powders. The microstructural analysis of sintered specimens will be carried out by X-ray diffraction, Raman spectroscopy and Scanning Electron Microscopy to look for correlations between microstructural and electrochemical impedance spectroscopy (EIS) results in thick pellets (0.5 - 5.0 um) and in films (0.1 - 100 um). Sintering will be carried out according to the following procedures: sintering under controlled atmosphere, fast firing sintering, two-step sintering, and liquid phase sintering using low melting point sintering aids. The following oxide compounds will be studied: zirconia and ceria based ionic conductors, barium and strontium cerate based proton conductors, and rare-earth manganite electron conductors. All these materials have in common their potential application in the development of two main kinds of devices: chemical species sensors and actuators, and oxide fuel cells for the clean production of electrical energy. The analysis of ceramic interfaces by EIS for determining blocking, frequency and capacitance factors, and the intergranular potential energy barriers, will help to establish correlations between intergranular phenomena and microstructure. This understanding will be used for the elaboration of experimental procedures for preparing ionic, protonic and electronic conducting oxides with optimized physical properties for best performance sensors and fuel cell devices. The project will take advantage of the experimental facilities and expertise of three laboratories of the University of S. Paulo: at IPEN for powder synthesis, microstructural analysis and impedance spectroscopy measurements, at EPUSP for powder synthesis and physical and chemical analysis of ceramic powders, and at IFUSP for powder synthesis and determination of the transport properties of Polycrystalline oxides.
