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 the X-Ray Diffraction 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 we conclude that these new lead-free materials have a good potential to replace lead-containing devices for microwave frequency applications.
