The tau(f) value of nearly 0 ppm/degrees C can be realized for x = 0.55, New high-quality dielectric ceramics having epsilon(r) of 85.3-89.9, Q.f values of 7510-8600 GHz, and tau(f) of 0-9 ppm/degrees C were obtained at 1150 degrees C for 3 h sintering in air, The influence of the sintering atmosphere on dielectric properties was also investigated.
