SiC added MgB2 polycrystalline samples were synthesized at low (650°C) and high (850°C) temperatures in order to study the sintering effect on the phase formation and superconducting properties. The MgB2 bulks with addition of 0wt%, 1wt%, 3wt% and 5wt% were studied with powder X-ray diffraction technique. We observed that MgB2 remained as the primary phase for both sintering temperature in all samples with the presence of MgO and Mg2Si as the main impurities. Some diffraction peaks associated with unreacted SiC is also noticeable. The intensity of the Mg2Si peaks was found to decrease in samples sintered at higher temperature. Temperature dependent magnetic moment measurement showed that the superconducting transition temperature, Tc decreases as the SiC addition level increases while lower sintering temperature degrade Tc to greater extent. The changes in the physical properties is discussed based on the results of phase formation, full width half maximum (FWHM), lattice parameter and crystallite size. 2010-11-12T07:55:13Z 2010-11-12T07:55:13Z 2010-06-09 Working Paper p.199-203 978-967-5760-02-0 http://hdl.handle.net/123456789/10187 en Proceedings of the International Conference on X-Rays & Related Techniques in Research & Industry (ICXRI) 2010 Universiti Malaysia Perlis School of Materials Engineering & School of Environmental Engineering |
