Abstract

The effects of CuO addition (1 and 2 wt%) on microstructures and microwave dielectric properties of CeO₂ ceramics with CuO additions have been investigated. It is found that CeO₂ ceramics can be sintered at 1490 °C due to the liquid phase effect of CuO addition. At 1580 °C, CeO₂ ceramics with 1 wt% CuO addition possesses a dielectric constant (ε_r) of 21.7, a Q × f value of 50,000 (at 9GHz) and a temperature coefficient of resonant frequency (τ_f) of -59 ppm/°C. A large sintering temperature reduction (about 200 °C) can be achieved by adding CuO to the CeO₂ ceramics. The CuO-added CeO₂ ceramics can find applications in microwave devices.
