Resumo
Nowadays, the La1-XSrXMnO3 (LSM) is one of the most common cathodic
materials used in the solid oxide fuel cells (SOFCs). The dopant strontium increases the
electronic conductivity of the material, besides presents an excellent electrochemical
performance, relatively good chemical and thermal stability and compatibility with solid
electrolyte of ZrO2/Y2O3 (YSZ). In this work, a contribution to the study of synthesis of LSM
is presented with strontium concentration of 50 mol % by the citrate technique. The powders
have been characterized for various techniques, as gas absorption and adsorption, X-ray
fluorescence spectroscopy, laser scattering granulometry, gas helium picnometry, scanning
electron microscopy (SEM), X-ray diffractometry (XRD) and calculations of theoretical
density and particle average diameter. The ceramics have been characterized by SEM and
XRD. The adequate characteristics of LSM have been evaluated aiming at the use in the
preparation of suspensions for cathodic thin films of SOFCs.
