Bi2O3-Tio2-Nd2O3 Lead-Free Material For Microwave Device Applications

Lead-free Bi2O3-TiO2-Nd2O3 system and its potential application for microwave devices applications were studied. The samples were synthesized using the melt quenching method. According to XRD analysis, the samples are polycrystalline with three different crystal phases. Measurements of the dielectric complex permittivity function were made at 2.7 GHz, using a resonant cavity and the small perturbation theory. The values of the dielectric permittivity of the prepared materials were compared with the commercial ones, and it was concluded that these new lead-free materials have good potential to replace lead-containing devices for microwave frequency applications.
