摘要：
The effect of different weight percentages of nano-Fe2O3 on the properties of Bi1.8Pb0⋅4Sr2Ca2Cu3O10+δ superconducting phase was studied. Phase formation, elemental real contents and granular microstructure of the investigated samples were carried out using X-Ray powder Diffraction (XRD), Energy Dispersive X-ray emission (EDX), Proton Induced X-ray Emission (PIXE), Rutherford Backscattering Spectrometry (RBS) and Scanning Electron Microscopy (SEM). XRD data indicated that the volume fraction of (Bi,Pb)-2223 decreased as nano-Fe2O3 wt.% increased. PIXE and EDX analyses showed that the PIXE technique is more accurate for detecting the nano-Fe2O3 than the EDX technique. The oxygen content, determined from RBS, decreased as nano-Fe2O3 wt.% increased.
