In the present work, a novel (1-x)BiVO₄-xLa_2/3MoO₄ scheelite related solid solution ceramics were prepared via solid state reaction method. As revealed by X-ray diffraction data, the crystal structure changed continuously from monoclinic to tetragonal phase at x = 0.10 and then the tetragonal solid solution was kept in a wide composition range up to x = 0.70. Both the Raman and far infrared spectra supported this phenomenon. When x value reached 0.9, the ceramic sample was found to composed of both scheelite tetragonal and monoclinic La_2/3MoO₄ phases. Large microwave permittivity value between 68 ± 0.2–73 ± 0.3 can be achieved in compositions with 0.02 ≤ x ≤ 0.10 with high Qf value about 10,000 ± 500 GHz. This series of solid solution ceramics might be candidate for both dielectric resonator and low temperature co-fired ceramic technology.

在本工作中，通过固相反应法制备了新型的（1-x）BiVO ₄ -xLa _2/3 MoO ₄白钨矿相关固溶陶瓷。如通过X射线衍射数据所揭示的，晶体结构在x ＝ 0.10处从单斜晶相连续变为四方晶相，然后将四方固溶体保持在高达x ＝ 0.70的宽组成范围内。拉曼光谱和远红外光谱均支持该现象。当x值达到0.9时，发现陶瓷样品由白钨矿四方晶和单斜晶La _2/3 MoO _4组成。阶段。在0.02≤x≤0.10且Qf值约为10,000±500 GHz的情况下，可以实现68±0.2–73±0.3的大微波介电常数。该系列固溶陶瓷可能是介电共振器和低温共烧陶瓷技术的候选者。
