Zr 0.8 Sn 0.2 )TiO 4 (ZST) ceramics were fabricated via conventional solid-state reaction method. Sintering behavior, phase composition, microstructure and microwave dielectric properties of Y 2 O 3 -ZnO doped ZST ceramics were investigated. Only a single ZST phase was identified by X-ray diffraction patterns. The variation tendencies of dielectric constants as well as Q 9 f values were in accordance with the bulk densities. The appropriate Y 2 O 3 and ZnO additions could not only efficiently lower the sintering temperature to 1240°C, but also noticeably improve the densification and microwave dielectric properties of ZST ceramics. But excessive additives deteriorated the microstructures and comprehensive properties of samples. A dielectric constant e r of 39.73, a Q 9 f value of 48,545 GHz (at 5.5 GHz), and a s f value of -2.13 ppm/°C were obtained for 1 wt% ZnO doped ZST ceramics with 0.5 wt% Y 2 O 3 addition sintered at 1240°C.
