The BaTiO3 sample was made by dry pressure, it was artificial spread nickel paste on BaTiO3, and it was simulated multilayer ceramic capacitors (MLCC¡¦s) to make a sandwich structure with BaTiO3-Ni-BaTiO3 by sintered in YAGEO¡¦s laboratories. The samples have been thoroughly analysis for the interface between BaTiO3 dielectric and Ni electrode or NiO oxide, by X-ray diffractometry, scanning electron microscopy, and transmission electron microscopy.
The interface between BaTiO3 and Ni has not orientation relationship as determined by selected area diffraction and it¡¦s not had dislocations in interface by two- beam image.
The NiO oxide as determined by XRD and TEM, because of the thermodynamic potential of the Ni/NiO equilibrium was produced. The array of dislocations of Burgers vector is 1/2[ 10] in the interface, and Burgers vectors are 1/2[00 ], [ 1 ] as determined by high resolution images and Fast Fourier Transform simulation. Misfit dislocations along the interface occur to accommodate the lattice mismatch.
