采用传统的固相法合成了Li_2Zn_xCo_1-xTi_3O_8（x = 0.2-0.8）固溶体体系，并研究了Zn替代Co对Li_2CoTi_3O_8陶瓷微波介电性能的影响。这些陶瓷的微波介电性能显示出所有组合物的端部成员之间的线性变化。Li 2 ZnxCo 1-xTi 3 O 8陶瓷的最佳烧结温度随Zn含量的增加而提高。在1050摄氏度/2小时下烧结的x = 0.4的样品表现出优异的微波介电性能组合，其中，τ（r）= 27.7，Q（u）x f = 57，100 GHz，τ（f）= -1.0 ppm/摄氏度。(c)出版社：Elsevier B. V.
The Li2ZnxCo1-xTi3O8 (x = 0.2-0.8) solid solution system has been synthesized by the conventional solid-state ceramic route and the effect of Zn substitution for Co on microwave dielectric properties of Li2CoTi3O8 ceramics has also been investigated. The microwave dielectric properties of these ceramics show a linear variation between the end members for all compositions. The optimized sintering temperatures of Li2ZnxCo1-xTi3O8 ceramics increase with increasing content of Zn. The specimen with x = 0.4 sintered at 1050 degrees C/2 h exhibits an excellent combination of microwave dielectric properties with epsilon(r) = 27.7, Q(u) x f = 57,100 GHz and tau(f) = -1.0 ppm/degrees C.
