Effect of Microwave Sintering on the Microstructure and Dielectric Properties of Bi2O3-Doped (Ba0.6Sr0.4)(Ti0.94Cu0.06)O3 Ceramics
Abstract: The effects of microwave sintering on the sintering behaviour, microstructure and dielectric properties of Bi2O3-doped (Ba0.6Sr0.4)(Ti0.94Cu0.06)O3 (BSTC) ceramics were investigated. The microstructure and dielectric properties of a BSTC ceramic were also studied given different amounts of Bi2O3 doping. Microwave heating with sintering temperatures below 1000°C significantly improves the densification of Bi2O3-doped BSTC ceramics. The BSTC ceramic with 1 wt% Bi2O3 addition sintered at 950°C in air for 30 min exhibited dielectric properties of er = 3756, dielectric loss of tanδ = 7 × 10-3 and bulk density > 96% of theoretical density.
