| Abstract The study included the preparation the samples of compounds (Bi2Ba2Ca2Cu3O10+d) by solid state reaction method and by using method of annealing temperature (1123 K) with hydraulic pressure 8 ton/cm2. The study obtained that the X-ray diffraction of compound (Bi2Ba2Ca2Cu3O10+d) have crystalline structure of Tetragonal type. When partial substitution of Cd element in Bi element to be the compound in formula (Bi2- xCdxBa2Ca2Cu3O10+d) with different rates of (x) it will be equal to (0.1,0.2,0.3,0.4). Where the results of the examination of the crystal structure that the installation remains conservative on the Tetragonal type. While increasing the critical temperature of (131K) to (138K) and that when increasing the value of (x) of (0.1) to (0.2). In the case of increase the value of (x) to (0.3,0.4) decreased the critical temperature and the change of compound from Tetragonal to Orthorhombic | ||
