| Abstract | ||
| This research includes preparing samples of the compound Bi2-xAgxSr2Ca2Cu3O10+δ by the solid state reaction under a hydrostatic pressure 8ton/cm2 and annealing temperature 1123 K . The best circumstances to obtain samples of the mentioned compound holding the superconductivity property at high temperatures .The study showed that X-ray diffraction when partial substitution of (Ag) in (Bi) in the compound to be Bi2-xAgxSr2Ca2Cu3O10+δ has been investigated where X = (0.1,0.2), the crystal structure remains tetragonal and the critical temperature increased from (110 K) to (129 K) due to increasing of oxygen content , then c-axis of the lattice increased as a result.through counting dimensions of crystal lattice (a,b,c) of compound (using of brack law) where X>0.2 (x=0.3) and above this rate. the crystal structure has also transformed to an orthorhombic. | ||
