The effects of nickel oxide doped BSCCO superconductors on structural, mechanical and electrical properties

In this thesis, it is aimed to improve superconductivity and electrical performance by investigating the effects of nickel oxide (NiO) additives on the basic properties of Bi-based superconducting ceramics. In line with this target, NiO additions between 0.0-1.2 molar ratios were made on the NiO metallic component Bi-2223 ceramics with the solid-state reaction method. The study was concluded by systematically interpreting the effects on the structural, mechanical, electrical, magnetic and superconducting properties of NiO-doped Bi-2223 ceramic samples. Superconducting samples were analyzed by performing X-ray diffraction (XRD), scanning electron microscopy (SEM), electrical resistivity (R-T), magnetization (M-H) and dynamic Vickers microhardness measurements.
