A novel high-performance Bi-based glass-Al2O3 composite system for LTCC applications
A novel high-performance Bi-based glass-Al2O3 composite material was successfully developed for low-temperature co-fired ceramic (LTCC) applications. The compositional effects of the binary glass of Bi2O3-ZnO-B2O3-Al2O3 (BZBA)+CaO-B2O3-SiO2 (CBS) on the phases, microstructures, microwave dielectric properties, and densification mechanism of the 45 wt% glass-55 wt% Al2O3 composite specimens were systematically studied. The optimal glass composition that could yield a high relative density (98.2%) and superior dielectric properties (εr= 8.7 and tanδ = 1.2 × 10−3) was confirmed to be 32.5 wt% BZBA+12.5 wt% CBS. Furthermore, based on the optimized composition, a complete fabrication process of the glass-Al2O3 composites by tape casting was performed, the sample was found to simultaneously have a low dielectric loss (1.0 × 10−3), a high mechanical strength level (300 MPa), a high thermal conductivity (4.25 W/m·K), and outstanding chemical compatibility with Ag electrode. The results indicate that the sample of 32.5 wt% BZBA+12.5 wt% CBS-55 wt% Al2O3 is a promising candidate material for LTCC applications.
期刊介绍：
The Journal of the American Ceramic Society contains records of original research that provide insight into or describe the science of ceramic and glass materials and composites based on ceramics and glasses. These papers include reports on discovery, characterization, and analysis of new inorganic, non-metallic materials; synthesis methods; phase relationships; processing approaches; microstructure-property relationships; and functionalities. Of great interest are works that support understanding founded on fundamental principles using experimental, theoretical, or computational methods or combinations of those approaches. All the published papers must be of enduring value and relevant to the science of ceramics and glasses or composites based on those materials.
Papers on fundamental ceramic and glass science are welcome including those in the following areas:
Enabling materials for grand challenges[...]
Materials design, selection, synthesis and processing methods[...]
Characterization of compositions, structures, defects, and properties along with new methods [...]
Mechanisms, Theory, Modeling, and Simulation[...]
JACerS accepts submissions of full-length Articles reporting original research, in-depth Feature Articles, Reviews of the state-of-the-art with compelling analysis, and Rapid Communications which are short papers with sufficient novelty or impact to justify swift publication.
