Synthesis and characterization of lanthanum strontium manganite

La0.85Sr0.15MnO3 (LSM) powder has been prepared by co-precipitation. Phase evolution studies by DTA, TGA and XRD indicated initiation of LSM formation above 750 °C. Densification behaviour of LSM powder with and without pore former was different. Sintered LSM was characterized for electrical conductivity, thermal expansion and microstructural development.
