摘要：

The dielectric properties and the microstructures of 0.6Ba(Co1/3Nb2/3)O-3-0.4Ba(Ni1/3Nb2/3)O-3 ceramics with CuO additions (0.25-1 wt%) prepared with conventional solid-state route have been investigated. It is found that 0.6Ba(Co1/3Nb2/3)O-3-0.4Ba(Ni1/3Nb2/3)O-3 ceramics can be sintered at 1270 degrees C due to the sintering aid of CuO addition. At 1270 degrees C, 0.6Ba(Co1/3Nb2/3)O-3-0.4Ba(Ni1/3Nb2/3)O-3 ceramics with 0.5 wt% CuO addition possesses a dielectric constant (epsilon(r)) of 32.5, a Q x f value of 82,000 (9 GHz) and a temperature coefficients of resonant frequency (tau(f)) of -21.2 ppm/degrees C. The CuO-doped 0.6Ba(Co1/3Nb2/3)O-3-0.4Ba(Ni1/3Nb2/3)O-3 ceramics can find applications in microwave devices requiring low sintering temperature. (C) 2007 Elsevier B.V. All rights reserved.
