Abstract
The Y257 superconductor was prepared by the melt process. The critical temperature of the sample is lower than sample prepared by solid state reaction. The sample are composed of 60% of superconducting phase and 40% of non-superconducting phase. The superconducting phase was orthorhombic structure and Pmmm space group symmetry. The EDX mapping indicated Y, Ba, Cu and O elements intermittently distribute in the sample. The TEM measurements indicated the SAD pattern of the single crystal and the polycrystalline. The DTA measurements indicated that the onset temperature were initially observed at around 999.848°C and offset temperature at 1018.680°C. The sample show the thermal reaction with endothermic reaction. © 2016 Trans Tech Publications, Switzerland.
