Notes:
Nowadays, the La1-XSrXMnO3 (LSM) is one of the most common cathodicmaterials used in the solid oxide fuel cells (SOFCs). The dopant strontium increases theelectronic conductivity of the material, besides presents an excellent electrochemicalperformance, relatively good chemical and thermal stability and compatibility with solidelectrolyte of ZrO2/Y2O3 (YSZ). In this work, a contribution to the study of synthesis of LSMis presented with strontium concentration of 50 mol % by the citrate technique. The powdershave been characterized for various techniques, as gas absorption and adsorption, X-rayfluorescence spectroscopy, laser scattering granulometry, gas helium picnometry, scanningelectron microscopy (SEM), X-ray diffractometry (XRD) and calculations of theoreticaldensity and particle average diameter. The ceramics have been characterized by SEM andXRD. The adequate characteristics of LSM have been evaluated aiming at the use in thepreparation of suspensions for cathodic thin films of SOFCs
