Sintering and Microwave Dielectric Characteristics of ZnTa2-xNbxO6 Ceramics

摘要：

　　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.
