Abstract

The effects of sintering aids additives on the microstructures and microwave dielectric properties of (1 - x)CaTiO3-xNd(Mg1/2Ti1/2)O3 ceramics were investigated. The effects of V2O5 additions on the microwave dielectric properties and the microstructures of (1 - x)CaTiO3-xNd(Mg1/2Ti1/2)O3 ceramics have been investigated. Doping with 0.5 wt% V2O5 can effectively promote the densification and the microwave dielectric properties of (1 - x)CaTiO3-xNd(Mg1/2Ti1/2)O3. It is found that CaTiO3-Nd(Mg1/2Ti1/2)O3 ceramics can be sintered at 1325 °C due to the liquid phase effect of a V2O5 additions. The dielectric constant decreases from 140 to 28 as x varies from 0.1 to 1.0. The microwave dielectric properties indicate the possibility of a phase transformation for x between 0.3 and 0.5. A low-pass filter is designed and simulated using the proposed dielectric to study its performance.
