Abstract :
Microwave dielectric properties of Ba(Zn13/Ta23/)O3-Ba(Cd13/Nb23/)O3 ceramics are presented. Sintering of Ba(Zn13/Ta23/)O3 was accelerated by the addition of Ba(Cd13/Nb23/)O3, and the microwave Q value was also improved. As ZnO volatilises from the sample, the crystallographic distortion was compensated, and the improved microwave loss quality, Q, was explained.
