Abstract
The microwave dielectric properties of Zn2(Sn(1−x)Zrx)O4 ceramics were examined with a view to their exploitation for mobile communication. The Zn2(Sn(1−x)Zrx)O4 ceramics were prepared by the conventional solid-state method with various amount of Zr substitution. The diffraction peaks of Zn2(Sn(1−x)Zrx)O4 ceramics did not vary significantly as x varied. A density of 6.10 g/cm3 was obtained for Zn2(Sn0.99Zr0.01)O4 ceramic, sintered at 1,225 °C for 4 h. Dielectric constant (ɛ r ) of 9.6, quality factor (Q × f) of 87,000 GHz, and temperature coefficient of resonant frequency (τ f ) of −51 ppm/°C were obtained for Zn2(Sn0.99Zr0.01)O4 ceramics that were sintered at 1,225 °C for 4 h.
