Abstract
This work consisted of the preparation of pure and ZnO-doped tin titanate zirconate (ZTS) by oxide mixture. Samples were sintered at temperatures ranging from 1200 to 1450 °C. An analysis was made of the influence of sintering on the microstructural development and dielectric properties of these materials at high frequencies. The liquid phase composition present during sintering was shown to be dependent on the ZnO percentage. This percentage determines grain composition and, hence, dielectric performance at high frequencies. A maximum loaded quality factor, Ql, of 1645 was found for 1.0 wt% ZnO-doped ZTS sintered at 1400 °C.
