Influence of Ti-Doping on Y257 Superconductor

Y257 Superconductor, Solid state reaction, Titaniumdoped


The bulk of Y257 doped with Ti was synthesized by solid state reaction. The formula of the Y257 are Y2Ba5Cu7TixO15-x, which x = 0, 0.05, 0.10, 0.15, 0.20, 0.25 mol. Critical temperatures were measured by using a standard four-probes technique. The surface and element analysis employed used the EDX mapping method. Thermal analysis was characterized by Differential Thermal Analysis (DTA). The maximum critical temperature value increased at a Ti concentration of 0.20 mol.
The surface of the samples has a Ti composite. The surfaces were smooth, denser and homogenous. The peritectic temperature of the Ti-doped samples was lower than the pure samples.
