- Abstract
The effects of the Ba(VO) (BV) additions on the phase composition, microstructures, sintering characteristics and microwave dielectric properties of (ZrSn)TiO (ZST) ceramics are investigated by an X-ray diffractometer, a scanning electron microscope and a network analyzer. The ZST and BV ceramics are all prepared by conventional solid-state method. BV can not only lower the sintering temperatures from 1650 to 1275 °C, but also speed up the grain growth of the ZST ceramics. But excessive additives deteriorate the microstructures and comprehensive properties of samples. As a result, ZST ceramics with 0.5 wt% BV can be well sintered at 1275 °C for 5 h and exhibit excellent microwave dielectric properties of ε = 36.6, Q × f = 46,000 GHz and τ = 1.47 ppm/°C.
