Abstract EN
The present study includes preparation of high temperature superconductor Bi2Sr2Ca2Cu3O10++& and Bi2Ba2Ca2Cu3O10++& by solid state reaction (SSR) method.
The prepared samples were calcinaed at 800oC for 20 hours ,then regrind and pressed at pressure (0.7 GPa) into pellets, then sintered at 860o C for sintering times (140,160,180 and 200) hr.
X-ray diffraction was used to determine the phases ,lattice constants (a,b&c ) and density of orthorhombic systems.
Then study effect of sintering time on both two compounds and compare between them ,the highest Tc recorded with sample (C) (Tc=103 K) for the compound Bi2Sr2Ca2Cu3O10++& at sintering time (ts=180 hr) ; and (Tc=96 K ) sample (L) for the compound Bi2Ba2Ca2Cu3O10+& at (ts=200 hr) it is the highest Tc recorded.
Also the study appeared prefer ability the first compound Bi2Sr2Ca2Cu3O10+& on the other Bi2Ba2Ca2Cu3O10+& because it records the highest Tc for same sintering times ,creasing number of peaks of HTS(2223),up rise intensity and drop value resistively for this search
