Abstract

The limited physical support offered by the substrate material significantly impedes the advancement of electronic components toward higher integration. In this study, the Er₂O₃–Al₂O₃–SiO₂ (EAS) glass–ceramics (GCs) with exceptional mechanical properties were synthesized through a conventional solid-phase method. The mechanical properties of EAS GCs were enhanced as the Er₂O₃ content increased to 51 wt.%, resulting in an ultrahigh flexural strength of 358.8 MPa, a Vickers hardness of 9.7 GPa, a fracture toughness of 2.87 MPa•m^1/2, and an elastic modulus of 158.9 GPa. These findings revealed that high crystallinity, fine grain size, and dense microstructure can effectively impede crack propagation and mitigate stress concentration, thereby endowing the material with substantial fracture energy and superior mechanical properties. The enhanced mechanical properties of EAS GCs make them a promising candidate for substrate applications.

提高Er2O3-Al2O3-SiO2微晶玻璃的力学性能

基板材料提供的有限的物理支持极大地阻碍了电子元件向更高集成度的发展。本文采用传统固相法合成了具有优异力学性能的Er2O3-Al2O3-SiO2 （EAS）微晶玻璃（GCs）。当Er2O3含量增加到51 wt.%时，EAS gc的力学性能得到增强，其超高抗弯强度为358.8 MPa，维氏硬度为9.7 GPa，断裂韧性为2.87 MPa•m1/2，弹性模量为158.9 GPa。研究结果表明，高结晶度、细晶粒尺寸和致密的微观组织可以有效地阻止裂纹扩展和减缓应力集中，从而使材料具有丰富的断裂能和优异的力学性能。EAS gc的力学性能增强，使其成为衬底应用的有希望的候选者。

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.
