In this Work, a detailed study of phase evaluation, Electric & magnetic properties of AxB1-xNb₂O₆Columbite Phase Material will be investigated. The material will be characterized for structural homogeneity, grain size improvement and Electromagnetic properties. The proposed outlines of the present project are following. 1. Synthesis of AxB1-xNb₂O₆ compounds by solid states and chemical routes. 2. Structural characterization of the phases and optimizing the parameter to obtain pure phase material. 3. Study of electrical (dielectric and impedance) and magnetic properties (Magnetic hysteresis loops and behavior of magnetic susceptibility with temperature and frequency) of these compounds and understands polarization and magnetization phenomena. 4. Compare the properties of bulk compounds and thin films.
In this proposal, a detailed study of preparation, structural characterization and electrical properties of some lead/ non lead relaxor materials will be investigated. The materials will be characterized for structural homogeneity, grain size improvement and electrical properties. The proposed outlines of the present project are as follows: • Synthesis of ABO3 (lead/lead free)-type compounds by solid state reaction route as well as chemical co-precipitation route • Structural characterization of these phases and optimizing the parameter to obtain the single phase. • Prepare the bulk compounds and thin films of these materials. • Compare the properties of solid and thin films. • Study the electrical behaviour of these materials and understand the relaxation mechanism.
The specific objectives of our project are: Develop single-phase nanocrystalline doped cubic zirconia and ceria electrolyte and compatible electrode materials by new chemical route/sol-gel/solid state route(ball mill)/liquid dispersion technique for intermediate operating temperature solid oxide fuel cells. To study and optimize the calcinations and sintering variables by using microwave heat treatment. Characterize the microstructure, phase evolution and electrical conductivity of SOFC components. How’s the nano-powder have an effect on sintering behavior and electrical properties of the electrolyte/electrode?
