The microstructure and dielectric properties of the complex perovskite Nd(Col/2Ti1/2)03ceramics with 60P2O5-15ZnO-5La2O3-5Al2O3-5N2O-5MgO-5Yb2O3glass additions from 1-2 wt% were prepared with the conventional solid-state route have been investigated. The resultant microwave dielectric properties were analyzed based upon the densification, the X-ray diffraction patterns and the microstructures of the ceramics. Doping with 60P2O5-15ZnO-5La2O3-5Al2O3- 5N2O-5MgO-5Yb2O3glass (up to 2 wt%) can effectively promote the densification of Nd(Co1/2Ti1/2)O3ceramics at low sintering temperature. A distinct sintering temperature reduction (100-200°C) can be achieved by adding 60P2O5-15ZnO-5La2O3-5Al2O3-5N2O-5MgO-5Yb2O3glass to the Nd(Co1/2Ti1/2)O3ceramics. The correlation between the microstructures and the microwave dielectric properties was also examined. The Nd(Co1/2Ti1/2)O3ceramics with 60P2O5-15ZnO-5La2O3- 5Al2O3-5N2O-5MgO-5Yb2O3glass additions can find applications in microwave devices requiring low sintering temperature. |
