| Abstract | ||
| ABSTRACT:The high Temperature (Tl2Ba2Ca2Cu3O10+) super conductors have been prepared using solid state reaction method .With different annealing temperature 8100C to 890 0C and two different hydraulic pressure 6 ton/cm2 to 9 ton/cm2 . It has been found that the optimum Tc has been obtained with pressure 8 ton / cm2 and 850 0C , So the critical temperature increased from 124 K to 130 K . The partial substitution effect of the Pb in Ti metal of the compound as Ti2- xPbxBa2Ca2Cu3O10+ has been investigated where x = 0.05 , 0.1 , 0.2,0.3 and 0.4 the critical temperature increased from 130 K to136 K due to increasing oxygen content and increasing C-axis by using X-ray diffraction .The study and examination of crystalline structure of samples by scanning electron microscopie completed with investigation the rate of elements in compound and the effect of annealing temperature with pressure in addition to partial substitution of elements of compound and determination the quantitative concentration rate of elements in the compound . | ||
