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, τf = -13.78 ppm/°C). The prepared ZnO-B2O3-SiO2/SiO2 composite is promising candidates for LTCC applications.
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.
