The Effect CuO Additive on the Microwave Dielectric Properties of Mg(Zr0.05Ti0.95)O3 Ceramics

Article Preview

Abstract:

The microwave dielectric properties of the Mg(Zr0.05Ti0.95)O3 ceramics with CuO addition were investigated. All specimens were prepared by solid-state reaction method and sintered at 1270-1420°C for 4 h. When CuO was added, the second phases of MgTi2O5, TiO2 and liquid phase were produced. For specimens with 1.5 wt% CuO sintered at 1300°C, the dielectric constant, Q´f and tf values are 18.2, 223000 GHz and -2 ppm/°C, respectively.
