Abstract EN
A ceramic superconductor compounds with the composition Bi2Sr2Ca2Cu3O10+δ were prepared alone or substituted by pb doped(Bi2-xPbxSr2Ca2Cu3O10+δ ) samples with different values of x =(0.1,0.35,0.4), and Al doped(Bi2 AlxSr2Ca2Cu3O10+δ ) samples with different values of x=(0.1,0.2,0.3) .The solid state reaction method was used for samples preparation .
From the principle routs like Bi-2223,Ca2CO3 and CuO with high purity 99.999% .
Superconducting phase was achieved by sintering (860o C) for (16 hours) .The slow cooling rate (1o C/min).was very important to the formation of superconducting time .The Bi-based system was multi phases .
Different measurement such as resistivity measurement , X-ray diffraction(XRD) and Scanning Electron Microscope(SEM) were made to show the improvement in the superconductivity of the high phase.
The crystal structures of stable superconducting compound of Bi2Sr2Ca2Cu3O10+δ was orthorhombic with lattice constant about a=5.394o A,b=5.346o A,c=30.753o A for low Tc phase and a=5.394o A,b=5.311o A,c=37.182o A for high phase .The critical temperatures (Tc) of the HTSC Bi2Sr2Ca2Cu3O10+δ were obtained to be Tc value for the un doped sample and for Pb, Al doped systems respectively and Scanning Electron Microscope(SEM) images showed formation plate-like or flake –like texture phases in superconducting samples.
