|Title:||Preparation of a perovskite La0.2Sr0.8CoO3-x membrane on a porous MgO substrate||Authors:||Hong, L.
|Issue Date:||Oct-2001||Citation:||Hong, L., Chen, X., Cao, Z. (2001-10). Preparation of a perovskite La0.2Sr0.8CoO3-x membrane on a porous MgO substrate. Journal of the European Ceramic Society 21 (12) : 2207-2215. ScholarBank@NUS Repository. https://doi.org/10.1016/S0955-2219(00)00320-4||Abstract:||Crack-free La0.2Sr0.8CoO3-x (LSCO-80) thin films have been fabricated on porous MgO substrates through dip coating followed by sintering. To avoid cracks in the LSCO-80 thin film during sintering caused by the shrinkage mismatch between the film and the substrate, a silver coating on top of the LSCO-80 powder casting layer prior to sintering was found effective. This paper focuses on the control of the porous structure of the MgO substrate, the preparation of sub-micron and narrowly distributed LSCO-80 powder, and the formulation of colloidal suspensions of LSCO-80 powder in an organic medium. The theme of the present work lies in exploiting dip-coating for fabricating a perovskite LSCO-x thin film on asymmetric porous substrates. © 2001 Elsevier Science Ltd.
