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 pelletized and then sintered furnace at 1400°C 2 Sintered pellets characterized study density, phase identification, crystalline size, microstructure, electric thermal properties. C...
