摘要：
Crystal structure and microwave dielectric properties of Ca[(Li1/3Nb2/3) Zr-0.95(0.05)]O3-delta-xTiO2(0 <= x <= 0.1) ceramics were investigated. A single phase with orthorhombic perovskite structure was obtained at x=0.02 similar to 0.1. With an increasing of Ti4+ content, the Qf value decreased due to a decrease of the degree of B-site 1:2 ordering. However, the tf value increased from-14.7ppm /degrees C to -6.9ppm/degrees C. When x=0.04, the optimum microwave dielectric properties: epsilon r=31.1, Qf =21640GHz and tau f =-8.8 ppm/degrees C.
