Abstract
In this paper synthesis of perovskite-type Lanthanum ferrites material which is done by soft chemical method using an organic combustion fuel is reported. The aim of this study is to evaluate the physical properties of Lanthanum ferrites material. Structural characterizations of the material were carried out by X-ray diffraction technique which revealed that the synthesized nano-structure was single phase with orthorhombic symmetry. The mean crystallite size of the sample was calculated by Scherer’s formula. Nano-sized Lanthanum ferrites material with specific surface area in the range of 18.3 m²/g and crystallite size in the range of 59 nm was obtained. The surface morphology examination was carried out by Scanning electron microscope. Transmission Electron Microscope investigations reveal that nano-materials with particle size in the range of 46 to 56 nm were obtained. The nano-size material synthesized by soft-chemistry combustion method showed better magnetic properties for applications as soft magnetic devices used in solid oxide fuel cells.
