Abstract

ZnO-B₂O₃-SiO₂/SiO₂ glass-ceramic composites are prepared by solid phase reaction method. The DSC curve of ZnO-B₂O₃-SiO₂ glass is analyzed and the effects of ZnO-B₂O₃-SiO₂ glass on the density, microwave dielectric properties, phase composition and microstructure of ceramic fillings are investigated. The results show that the sintering temperature of the composites can be reduced to 910 °C by adding ZBS glass. When the addition of ZBS is 65% (wt%), the dielectric properties of the sample are best when the composite is sintered in 910 °C for 1 h (εr = 4.6, tanδ = 4.85 × 10^− 4 at 9.2 GHz, τ_f = -13.78 ppm/°C). The prepared ZnO-B₂O₃-SiO₂/SiO₂ composite is promising candidates for LTCC applications.

用于 LTCC 应用的超低介电常数和介电损耗 ZnO-B2O3-SiO2 玻璃/二氧化硅复合材料的合成、微观结构和特性分析

采用固相反应法制备了 ZnO-B2O3-SiO2/SiO2 玻璃陶瓷复合材料。分析了 ZnO-B2O3-SiO2 玻璃的 DSC 曲线，并研究了 ZnO-B2O3-SiO2 玻璃对陶瓷填料的密度、微波介电性能、相组成和微观结构的影响。结果表明，加入 ZBS 玻璃后，复合材料的烧结温度可降低到 910 ℃。当 ZBS 的添加量为 65% （重量百分比）时，复合材料在 910 °C 下烧结 1 小时后，样品的介电性能最佳（εr = 4.6，9.2 GHz 时 tanδ = 4.85 × 10- 4，τf = -13.78 ppm/°C）。制备的 ZnO-B2O3-SiO2/SiO2 复合材料有望用于 LTCC 应用。

期刊介绍： While ceramics have traditionally been admired for their mechanical, chemical and thermal stability, their unique electrical, optical and magnetic properties have become of increasing importance in many key technologies including communications, energy conversion and storage, electronics and automation. Electroceramics benefit greatly from their versatility in properties including: -insulating to metallic and fast ion conductivity -piezo-, ferro-, and pyro-electricity -electro- and nonlinear optical properties -feromagnetism. When combined with thermal, mechanical, and chemical stability, these properties often render them the materials of choice. The Journal of Electroceramics is dedicated to providing a forum of discussion cutting across issues in electrical, optical, and magnetic ceramics. Driven by the need for miniaturization, cost, and enhanced functionality, the field of electroceramics is growing rapidly in many new directions. The Journal encourages discussions of resultant trends concerning silicon-electroceramic integration, nanotechnology, ceramic-polymer composites, grain boundary and defect engineering, etc.
