Abstract

Dielectrics (Zn,Mg)TiO₃, having a high dielectric constant and a near zero temperature coefficient of resonant frequency are promising materials for microwave applications. In this work, Bi₂O₃ was added to (Zn,Mg)TiO₃ as a low-temperaturesintering dopant. The addition of Bi₂O₃ significantly improved the densification of (Zn,Mg) TiO₃, which were densified below 1000°C. In addition, the decomposition temperature of (Zn,Mg)TiO₃ increased as the magnesium substitution increased. Microwave dielectric properties of (Zn,Mg)TiO ₃ ceramics depend on crystalline structure. By properly adjusting the amount of magnesium, a small temperature coefficient of resonant frequency was obtained for (Zn,Mg)TiO₃ dielectrics.
