Abstract: Two high frequency dielectric systems of ZnO-B2O3-SiO2 and BaO-PbO-Nd2O3- Bi2O3-TiO2 were prepared by conventional ceramics technology. Through XRD analysis, the main crystal phases were determined. The volume percentage contents of each phase were calculated according to the X-ray diffraction peak intensity. Then, these data were introduced into Lichnetecker Law, from which the dielectric properties of the systems were obtained. This is a new way to analyze quantitative relationship between the dielectric properties and phase contents of dielectric materials.
