Abstract
Ceramics in the system (1 − x)(Mg0.95Zn0.05)TiO3–x(Na0.5Nd0.5)TiO3 were prepared by the conventional mixed oxide route. It shows a two-phase system of an ilmenite structured (Mg0.95Zn0.05)TiO3 and a perovskite structured (Na0.5Nd0.5)TiO3, which were confirmed by XRD and EDX. In addition, (Mg0.95Zn0.05)Ti2O5 was identified as a second phase. It was also responsible for a rapid drop in the Q × f value. The temperature coefficient of resonant frequency was a function of compositional ratio. Specimen with x = 0.16 possessed an excellent combination of microwave dielectric properties: εr ~ 24.27, Q × f ~ 82,000 GHz (at 9 GHz) and τf ~ 0 ppm/°C.
