Abstract

In this research, two samples were manufactured by the solid-state reaction method and using two methods of sintering and annealing, under a pressure of 8 ton/cm² and a temperature of 820 ℃. In the first sample, the nickel element Ni was partially replaced by the copper element Cu at a ratio of X=1, and in the second sample the nickel element Ni was partially replaced by the copper element Cu by X=2 to become the compound Bi2Ba2Ca2Cu3-xNixO10+δ. The unit cell dimension values were: a = 5.4179 (Å), b = 5.5786 (Å), C = 36.5693 (Å), c/a ratio = 6.7498, density = ρm (g/cm3) = 6.7210, and HTP% = 70.34%. From observing the values It has an orthorhombic structure, and when = c/a and the density is 6.7388 = ρm (g/cm3) and HTP% = 67.17%. From observing the values, they are of an orthorhombic structure. Examinations of the two models in the SEM device showed the first model When x=1 At 30.00kx magnification, the grain size formation ranging from 191.6nm to 492.3nm was found to be clear and homogeneous. As for the second model, when x=2 With a magnification power of 30.00kx, a formation of grain size ranging from 96.89 nm to 6 343 nm was found, with clear, homogeneous, and compact images.
