| Abstract: | The XRD pattern character, structure and relative diffraction intensity I_(100)/I_(110) of Sr_(1-x)Ca_xTiO_3 and Sr_(1-x)Pb_xTiO_3 ceramics with perovskite structure were investigated. The samples were prepared by using usual technique of the electronic ceramics preparation. Based on the relation between atomic scattering factor and diffraction intensity, we put forward a method to forecast the kind of ions on A site of the perovskite structure by using diffraction intensity I_(100)/I_(110) change of the solid solutions with ABO_3 perovskite structure. |
