Article Preview

The compound strontium-doped manganite lanthanum (La0,85Sr0,15MnO3 - LSM), deposited in the form of thin films in yttria-stabilized zirconia substrate (Y2O3/ZrO2 - YSZ), is of basic importance as cathodic material of the solid oxide fuel cells (SOFC). In this work, the LSM was synthesized by the citrate technique and characterized by X-ray fluorescence spectroscopy (XRF), phase analysis light scattering granulometry (PALS), X-ray diffractometry (XRD) and scanning electron microscopy (SEM). In the wet powder spraying, was used an airbrush and the LSM sample deposited to the YSZ substrate was sintered and characterized by SEM. The conclusions had allowed to establish preliminary conditions for preparation of LSM suspensions by wet powder spraying.
