Abstract

A series of hexagonal perovskite Ba₁₂M_0.5Zr_0.5Nb₉O₃₆ (M = Ni, Mg, Co, Zn) ceramics were prepared by solid-state reaction method. XRD and Rietveld refinement results showed that all ceramic samples belong to the hexagonal perovskite structure with R-3m space group. With different B-site ion substitution, variation of permittivity (ε_r) can be ascribed to the average ion polarizability. Ceramics with highest relative density exhibit maximum quality factor (Q×f) values. Among all samples, the optimal microwave dielectric properties of ε_r = 35.2, Q×f = 57,985 GHz, and τ_f = 26.4 ppm/°C for Ba₁₂Mg_0.5Zr_0.5Nb₉O₃₆ were obtained, which indicated that Ba₁₂Mg_0.5Zr_0.5Nb₉O₃₆ ceramic is a candidate material for microwave communication applications.

具有六方包晶结构的 Ba12M0.5Zr0.5Nb9O36（M=镍、镁、钴和锌）微波介电陶瓷系列

采用固态反应法制备了一系列六方包晶Ba12M0.5Zr0.5Nb9O36（M = Ni、Mg、Co、Zn）陶瓷。XRD 和里特维尔德细化结果表明，所有陶瓷样品都属于 R-3m 空间群的六方包晶结构。随着 B 位离子取代度的不同，介电常数（εr）的变化可归因于平均离子极化率。相对密度最高的陶瓷表现出最大的品质因数（Q×f）值。在所有样品中，Ba12Mg0.5Zr0.5Nb9O36 的最佳微波介电性能为 εr = 35.2、Q×f = 57,985 GHz 和 τf = 26.4 ppm/°C，这表明 Ba12Mg0.5Zr0.5Nb9O36 陶瓷是微波通信应用的候选材料。

期刊介绍： Ceramics International covers the science of advanced ceramic materials. The journal encourages contributions that demonstrate how an understanding of the basic chemical and physical phenomena may direct materials design and stimulate ideas for new or improved processing techniques, in order to obtain materials with desired structural features and properties. Ceramics International covers oxide and non-oxide ceramics, functional glasses, glass ceramics, amorphous inorganic non-metallic materials (and their combinations with metal and organic materials), in the form of particulates, dense or porous bodies, thin/thick films and laminated, graded and composite structures. Process related topics such as ceramic-ceramic joints or joining ceramics with dissimilar materials, as well as surface finishing and conditioning are also covered. Besides traditional processing techniques, manufacturing routes of interest include innovative procedures benefiting from externally applied stresses, electromagnetic fields and energetic beams, as well as top-down and self-assembly nanotechnology approaches. In addition, the journal welcomes submissions on bio-inspired and bio-enabled materials designs, experimentally validated multi scale modelling and simulation for materials design, and the use of the most advanced chemical and physical characterization techniques of structure, properties and behaviour. Technologically relevant low-dimensional systems are a particular focus of Ceramics International. These include 0, 1 and 2-D nanomaterials (also covering CNTs, graphene and related materials, and diamond-like carbons), their nanocomposites, as well as nano-hybrids and hierarchical multifunctional nanostructures that might integrate molecular, biological and electronic components.
