Two models were prepared for this research by solid-state reaction method, using the annealing method, at a pressure of 8 tan/cm² and a temperature of 800 ℃. In the first model, the element Ni was partially replaced by the element Cu in a ratio of x=1 to become the compound Bi2Ba2Ca2Cu3-xNixO10+δ, and in the second model the element was partially replaced Ni with the element Cu by x=2 The electrical tests of the first model showed a significant increase in the value of the critical temperature, where the critical temperature Tc reached a value of 136.5 k, and in the second model the critical temperature reached 130 k The structural properties of the X-ray diffraction of the models showed the presence of a specific phase So that when x=1 a=(5.4179) A° b=(5.5786) A°, c=(36.5693) A° And when x=2 kept the rhombic phase a=(5.4311) A°, b=(5.5531) A°, c=(36.3926) A°, while an increase in the value of c=(36.5693) A° when x=1 showed Examinations of the two models in the SEM device The first model with a magnification of 100.00kx found the formation of granular size ranges from 37.19nm to 457.1nm with a magnification of 500kx found the formation of light-colored homogeneous blocks, while the second model with a magnification of 100.00kx found the formation of granular size ranging from 227.5nm to 485.3nm with a magnification of 500kx The formation of a homogeneous light-colored mass with clear and compact images. The magnetic tests showed that the hysteresis rings formed in the two models are very narrow and that there is a completely inverse relationship between the tightness of the rings and the improvement of the critical temperature. Tc This applies to the two models, as the tightness of the hysterics rings in the second model is greater than the tightness of the hysterics rings in the first model.

In this study two Ferroelectric compounds were prepared, The chemical formula of the two compounds were [BTO] and [BPTO], Both compounds were synthesized by ceramic method and calcined for 4 hours at 1000°C. Then, the compounds were subjected to X-ray diffraction Analysis for the determination of their structural properties.From the results, the compounds were found to exhibit a tetragonal Perovskite with homogenous particle size in-between the samples; furthermore, there was an observable increase in the Theoretical density. Similarly, Samples were subjected to atomic force Microscope (AFM) analysis for roughness, grain size, and root mean square.Upon Infrared analysis of the samples, the IR spectra showed an increase in the constant bond force (K) by a slight proportion of lead while the bond length (r) decreased by the same proportion.
