1:2 ordered Ba₃Zn(Nb_2-xMo_x)O_9+x/2(BZNM) ceramics with space group $\text{P}\overline{3}\text{ml}$ were prepared by solid-state method. The nature of chemical bonds in Ba₃Zn(Nb_2-xMo_x)O_9+x/2(BZNM) ceramics was investigated for the first time. Firstly, the bond energy was closely related to the lattice vibration. High bond energy would lead to weak non-harmonic interactions, which were the main factors of improving Qf. Secondly, polarization of the chemical bond was the principal contributor to the relative permittivity of microwave ceramics. Compared with the traditional method, the calculated result based on the P-V theory reduced the error from 81% to 4.4%. Through the discussion, it was confirmed that the analysis method based on chemical bond was highly feasible and scientific in the microwave ceramics. At last, the system of Ba₃Zn(Nb_1.992Mo_0.008)O_9.004 sintered at 1435 °C for 6 h and annealed at 1300 °C for 10 h had excellent microwave dielectric properties: ε_r = 38.9, Qf = 102,931 GHz, τ_f = 19.2 ppm/°C, which, to our best knowledge, provided a alternative for the application of millimeter-wave communications.

具有空间群的1：2有序Ba ₃ Zn（Nb _2-x Mo _x）O _{9 + x / 2}（BZNM）陶瓷$\text{P}\overline{3}\text{毫升}$通过固态方法制备。首次研究了Ba ₃ Zn（Nb _2-x Mo _x）O _{9 + x / 2}（BZNM）陶瓷中化学键的性质。首先，键能与晶格振动密切相关。高键能会导致弱的非谐波相互作用，这是提高Q f的主要因素。其次，化学键的极化是微波陶瓷相对介电常数的主要贡献者。与传统方法相比，基于PV理论的计算结果使误差从81％降低到4.4％。通过讨论，证实了基于化学键的分析方法在微波陶瓷中是高度可行和科学的。最后，Ba ₃ Zn（Nb _1.992 Mo _0.008）O _9.004在1435°C烧结6 h并在1300°C退火10 h的体系具有优异的微波介电性能：_εr  = 38.9，Q f  = 102,931 GHz ，τ _˚F = 19.2 ppm /°C，据我们所知，这为毫米波通信的应用提供了一种替代选择。
