A series of high-temperature superconducting samples of type Cu0.5Tl0.5Ba2Ca2Cu3O10-δ, (Cu0.5Tl0.5)-1223, added with nano-Fe2O3 (0.0- 1.0 wt. %) was prepared by a solid-state reaction technique via short time preparation procedure and under ambient pressure. The prepared samples were characterized using X-ray powder diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive X-ray (EDX) for phase analysis and microstructure examination. The volume fraction results indicated that nano-Fe2O3 addition was significant in enhancing the formation rate of the (Cu0.5Tl0.5)-1223 phase, especially for x ≤ 0.2 wt. % samples. The electrical resistivity of the prepared samples was measured by the conventional four-probe technique from …
