Abstract
The (Zr0.8Sn0.2)TiO4 material (ZST), has been prepared by solid state reaction and characterized. The samples were sintered in the temperature range of 1050–1300 °C for 2 h. The effects of sintering parameters like sintering temperature and CuO addition (1–3 wt. %) on structural and dielectric properties were investigated. Bulk density increases from 4.4 to 5.2 g/cm3 with the increase of sintering temperature and adding elements. The effect of CuO addition is to lower the sintering temperature in order to obtain well sintered samples with high value of bulk density. The material exhibits a dielectric constant of 38.2 and high values of the Q.f product, greater than 60000, at microwave frequencies. The dielectric properties make the ZST material very attractive for microwave applications such as dielectric resonators, filters, dielectric antennas, substrates for hybrid microwave integrated circuits, etc.
