Microwave Dielectric Properties of Ca[(Li_1/3Nb_2/3)_0.95Zr_0.05]O_3−δ−xTiO₂ Ceramics

Abstract:

Crystal structure and microwave dielectric properties of Ca [(Li_1/3Nb_2/3) _0.95Zr_0.05]O_3−δ−xTiO₂(0≤x≤0.1) ceramics were investigated. A single phase with orthorhombic perovskite structure was obtained at x=0.02~0.1. 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 τf value increased from-14.7ppm /°C to-6.9ppm/°C. When x=0.04, the optimum microwave dielectric properties: εr=31.1, Qf =21640GHz and τf =−8.8 ppm/°C.
