The target of the research was producing an LSM perovskite with a low resistivity, what was reached by the systematic optimization of high-energy ball milling (HEBM) (optimal time 3h), and sintering profile with a max of 1200 deg.C. Increase in calcination temperature shown to decrease resistivity. The high temperature was both increasing the reaction extent and compactness of the specimen.
