La0. 80Sr0. 20MnO3 perovskite material is synthesized by conventional solid state reaction
method. Raw materials in stoichiometric ratio are ball milled with use of zirconium oxide
balls for six hours. Calcined powder is pelletized and then sintered by use of conventional
furnace at 1400oC for 2 hours. Sintered pellets are characterized for study of density, phase
identification, crystalline size, microstructure, electric and thermal properties. Crystalline size
of the as prepared sample is found to be 52 nm. Thermo-gravimetric analysis shows weight …
