摘要

(Ca_0.7Nd_0.3) (Ti_0.7Al_0.3)O₃ microwave dielectric ceramics with different contents of Al₂O₃ were prepared. The inference of Al₂O₃ on the sintering characters, dielectric properties and microwave structures of the (Ca_0.7Nd_0.3) (Ti_0.7Al_0.3)O₃ ceramics was studied by XRD, SEM, EDS and so on. The results showed that the addition of Al₂O₃ did not change the main crystal phase, and promoted the growth of the crystal grain and reduced the sintering temperature efficiently. With the increase of the content of Al₂O₃, the εr does not change significantly, but the Q×f values can be up to the maximum of 25 153 GHz.
