Article Preview

The effects of Nb2O5 content upon the microwave characteristics of ZnTa2−xNbxO6 ceramics are investigated. The appropriate sintering temperatures of ZnTa2−xNbxO6 ceramics slightly decrease with the increase of Nb2O5 content, and the densities and dielectric constants of ZnTa2−xNbxO6 ceramics linearly decrease with the increase of Nb2O5 content. As the Nb2O5 content increases, the Q×f value of ZnTa2−xNbxO6 ceramic first decreases, reaches a minimum value at x=1.0, then increases and reaches a maximum value at x=2.0. The τf values of ZnTa2−xNbxO6 ceramics are positive for x≤0.3, and change to negative ones as x≥0.6.
