Abstract

In this study, pure phase strontium-doped lanthanum manganite, La0.75Sr0.25MnO3 (LSM), with a hexagonal structure was synthesized by solid state reaction at different grinding times. The required phase has formed short grinding time only at 15 minutes and has particle size in nano scale as a result of effect of mechanical grinding. Physical properties of prepared sample will be investigated especially grain size and strain in order to study the effect of mechanical grinding on phase formation.
