- Abstract
- Bi2O3 was added to a nominal composition of Zn1.8SiO3.8 (ZS) ceramics to decrease their sintering temperature. When the Bi2O3 content was < 8.0 mol%, a porous microstructure with Bi-4(SiO4)(3) and SiO2 second phases was developed in the specimen sintered at 885 degrees C. However, when the Bi2O3 content exceeded 8.0 mol%, a liquid phase, which formed during sintering at temperatures below 900 degrees C, assisted the densification of the ZS ceramics. Good microwave dielectric properties of Q x f=12,600 GHz, epsilon(r)=7.6, and tau(f)=-22 ppm/degrees C were obtained from the specimen with 8.0 mol% Bi2O3 sintered at 885 degrees C for 2 h.
