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 Bi4 (SiO4)3 and SiO2 second phases was developed in the specimen sintered at 885°C. However, when the Bi2O3 content exceeded 8.0 mol%, a liquid phase, which formed during sintering at temperatures below 900°C, assisted the densification of the ZS ceramics. Good microwave dielectric properties of Q × f = 12,600GHz, εr = 7.6, and τf = -22 ppm/°C were obtained from the specimen with 8.0 mol% Bi2O3 sintered at 885°C for 2 h.
