Abstract

Yttrium aluminum garnet (YAG) transparent ceramics, owing to their outstanding optical properties and thermal stability, are widely applied in lasers, optical windows, and other fields. Numerous studies have focused on the optimization of their preparation processes and performance, and many laws governing the relationship between ball-milling processes and optical quality have been established. However, the conclusions vary significantly across different studies. This variation is attributed to the differences in the input conditions of each study, such as the state of the precursor materials. In this study, based on the mass transport behavior during sintering densification, the direct effect of the precursor Y2O3/Al2O3 particle size, especially their corresponding ratio, instead of the ball-milling method, on the optical quality of YAG transparent ceramics was systematically explored. The optimal particle size ratio was established, and YAG transparent ceramics with an in-line transmittance of 84.3% at 800 nm were successfully fabricated. A new heterogeneous contact model was proposed to reveal the relationship between precursor powder particle size and optical performance of ceramics. This work provides a new perspective on optimizing precursor particle characteristics for fabricating high-performance transparent ceramics.

采用非均相接触模型优化YAG高透明陶瓷的粒径比

钇铝石榴石（YAG）透明陶瓷由于其优异的光学性能和热稳定性，被广泛应用于激光、光学窗等领域。许多研究都集中在其制备工艺和性能的优化上，并建立了许多控制球磨工艺与光学质量之间关系的规律。然而，不同研究的结论差异很大。这种差异归因于每个研究的输入条件的差异，例如前驱体材料的状态。本研究基于烧结致密化过程中的质量输运行为，系统探讨了Y2O3/Al2O3前驱体粒径，特别是其对应比例对YAG透明陶瓷光学质量的直接影响，而不是采用球磨法。确定了最佳粒径比，成功制备了800 nm透射率为84.3%的YAG透明陶瓷。提出了一种新的非均相接触模型，揭示了前驱体粉末粒度与陶瓷光学性能之间的关系。本研究为制备高性能透明陶瓷提供了优化前驱体颗粒特性的新思路。

期刊介绍： Applied Physics Letters (APL) features concise, up-to-date reports on significant new findings in applied physics. Emphasizing rapid dissemination of key data and new physical insights, APL offers prompt publication of new experimental and theoretical papers reporting applications of physics phenomena to all branches of science, engineering, and modern technology. In addition to regular articles, the journal also publishes invited Fast Track, Perspectives, and in-depth Editorials which report on cutting-edge areas in applied physics. APL Perspectives are forward-looking invited letters which highlight recent developments or discoveries. Emphasis is placed on very recent developments, potentially disruptive technologies, open questions and possible solutions. They also include a mini-roadmap detailing where the community should direct efforts in order for the phenomena to be viable for application and the challenges associated with meeting that performance threshold. Perspectives are characterized by personal viewpoints and opinions of recognized experts in the field. Fast Track articles are invited original research articles that report results that are particularly novel and important or provide a significant advancement in an emerging field. Because of the urgency and scientific importance of the work, the peer review process is accelerated. If, during the review process, it becomes apparent that the paper does not meet the Fast Track criterion, it is returned to a normal track.
