Abstract
Solid solution ceramics in the Ba(Zn1/3Nb2/3)O3-Sr(Zn1/3Nb2/3)O3 system have been studied in view of finding materials for use as dielectric resonators at microwave frequency. The relative dielectric constant of Ba(Zn1/3Nb2/3)O3 and Sr(Zn1/3Nb2/3)O3 ceramics is 41 and 40, and the unloaded Q is 7500 and 4000 at 9 GHz respectively. A nearly zero temperature coefficient of resonant frequency is obtained for a solid solution ceramic with 0.35 BZN-0.65 SZN. The temperature dependence of dielectric constant is discussed in terms of the Clausius-Mossotti relation.Keywords
