摘要:

Microwave ceramic resonators composed of BaO‐TiO2‐WO3were developed. The effect of WO3addition on the system of BaO·xTiO2·(1+x)yWO3(x=4 and 4.5, y=0 to 0.04) was studied. The ceramics of this system are composed of crystallines including Ba2Ti9O20, BaTi4O9, BaWO4, and TiO2. At y=0.02, the BaO·4TiO2·0.1WO3ceramic was found to have excellent microwave properties such as ε=35, Q=8400 at 6 GHz, and nearly 0 ppm/
