【Abstract】 The solid solution behavior of double-sites incorporation of two sets of(Ce,Sr) and(Zr,Sr) in barium titanate has a great research value on the development of high-k materials and high-k diffusion efficiency at room temperature.Barium titanate ceramics co-doped with two sets of ions mentioned above were prepared by the cold-pressed ceramic technique.X-ray Diffraction spectra were measured.By comparison with the incorporation of Sr into Ba-sites,the influence of double-sites incorporation of Ce and Sr,Zr and Sr in barium titanate lattice on the solid solution was evaluated.更多还原
