In the present work, the influence of various heat treatment conditions such as sintering temperature, duration and compacting pressure, on the structure, microstructural and electrical properties of the new Y3Ba5Cu8Oy (noted Y-358, YBCO family)superconducting material was investigated. Samples were produced by means of the standard solid-state reaction process. The structural and microstructural characterizations of the various synthesized products were investigated by X-ray diffraction (XRD) and scanning electron microscope (SEM). The electrical resistivity as a function of temperature was also performed and examined. The analyses show that the optimal structural formation was achieved for the product prepared at 950°C for 48 h. This sample exhibited a superconducting transition temperature (Tco) value around 95 K.
Key words: Y3Ba5Cu8Oy superconductor, Structure, Morphology, Transport properties.
