The microstructure and dielectric properties of the complex perovskite Nd(Co1/2Ti1/2)O3 ceramics with 60P2O5-15ZnO-5La2O3-5Al2O3-5N2O-5MgO-5Yb2O3 glass 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-5Yb2O3 glass (up to 2 wt%) can effectively promote the densification of Nd(Co1/2Ti1/2)O3 ceramics at low sintering temperature.A distinct sintering temperature reduction (100-200℃) can be achieved by adding 60P2O5-15ZnO-5La2O3-5Al2O3-5N2O-5MgO-5Yb2O3 glass to the Nd(Co1/2Ti1/2)O3 ceramics.The correlation between the microstructures and the microwave dielectric properties was also examined.The Nd(Co1/2Ti1/2)O3 ceramics with 60P2O5-15ZnO-5La2O3-5Al2O3-5N2O-5MgO-5Yb2O3 glass additions can find applications in microwave devices requiring low sintering temperature.
