Effects of ZBS addition on crystallization, microstructure and dielectric properties of low temperature co-fired Mg2SiO4-CaTiO3 ceramics
The 0.9Mg2SiO4-0.1CaTiO3 (MSCT) ceramics with 60ZnO-20B2O3-20SiO2 glass (ZBS) and LiF compound additives were prepared by solid-state reaction method. The effects of different ZBS contents on the phase, densification temperature, surface morphology and dielectric properties of MSCT ceramics were studied. The results show that ZBS can inhibit the reaction between LiF and CaTiO3, which improve the surface morphology and reduce the sintering temperature of MSCT ceramics. The sample of MSCT with 2wt%ZBS-1.5wt%LiF sintered at 900 °C for 90 min shows excellent microwave dielectric properties: εr = 9.26, Q × f = 68,580 GHz (at 15.5 GHz) and τf = -1.49 ppm/ °C. There is no obvious element diffusion at the co-firing interface between dielectrics and Ag electrodes, indicating it is a promising candidate 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.
