Cold sintering is an emerging technology that enables processing of ceramics and composite materials at temperatures around 100 degrees Celsius, compared to traditional processes typically requiring longer times at kiln temperatures around 1000 degrees. This inherent energy reduction in processing enables unprecedented integration of materials to create new composites. The integration of organic and inorganic materials also provides a unique opportunity for the reuse of composites, thereby enhancing sustainability through both waste reduction and energy savings. The U.S. has established research leadership in cold sintering over the past decade. The project stands to extend this leadership into the manufacturing realm by validating a pilot-scale process for materials used in electrical capacitors. Through a partnership with the American Ceramic Society and the Pennsylvania Technical Assistance Program (PennTAP), the team will outline educational workshops to accelerate adoption of cold sintering by industry researchers. The workshops, focused on bringing students from vocational schools to Penn State for summer experiences, could serve as a pilot model for larger efforts focused on integrating vocational schools with research-intensive universities. The project will develop proof-of-concept demonstrations needed for translation of cold sintering to manufacturing of capacitors. Cold sintering relies on an applied uniaxial pressure and a transient solvent to reduce the sintering temperature of ceramics by approximately an order magnitude, down to about 100 degrees Celsius. This opportunity for co-sintering of polymers and ceramics creates an approach for the synthesis of re-processable composites. As such, the proposed work will drive advanced composites towards a circular economy, by demonstrating the synthesis of reformable composites, and by reducing the energy cost of re-processing. The specific goals of this project include the development of a pilot-scale process, the development of acoustic-based characterization tools, and the optimization of processing conditions to ensure uniformity of cold sintered composites used in capacitors. Foundational knowledge on process optimization will be obtained through in-situ techniques, specifically impedance spectroscopy, post-process nondestructive characterization through acoustic methods, and integrated data analytic techniques as supported by machine learning. The optimized processes will benefit a variety of applications where sintering at reduced temperatures is valuable, including energy storage, structural materials, thermal management, and electronic devices. Integration of research, education, and workforce development will be key to advancing cold-sintering research from the lab to commercial manufacturing.This project is jointly funded by the CBET Division of the Engineering Directorate and the CHE Division of the Mathematics and Physical Sciences Directorate.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

冷烧结是一种新兴技术，与通常在1000度左右的窑炉温度下需要更长的时间相比，在摄氏100摄氏度左右的温度下，可以处理陶瓷和复合材料。加工中的这种固有的能量减少可以使材料的前所未有的整合能够创建新的复合材料。有机和无机材料的整合也为复合材料的再利用提供了独特的机会，从而通过减少废物和节能来增强可持续性。 在过去的十年中，美国在寒冷烧结方面建立了研究领导。 该项目将通过验证电容器中使用的材料的试点规模的流程，将该领导力扩展到制造领域。通过与美国陶瓷协会和宾夕法尼亚州技术援助计划（PENNTAP）的合作，该团队将概述教育研讨会，以加速行业研究人员对冷烧结的采用。这些讲习班的重点是将职业学校的学生带到宾夕法尼亚州立大学，以供夏季体验，可以作为大型努力的试点模型，专注于将职业学校与研究密集型大学相结合。该项目将开发概念验证示范，将冷烧结转换为电容器制造所需。冷烧结依赖于施加的单轴压力和瞬时溶剂来降低陶瓷的烧结温度，大约降低至约100摄氏度。共同插入聚合物和陶瓷的机会为合成可重新加工的复合材料创造了一种方法。因此，拟议的工作将通过证明可改革复合材料的综合并减少重新处理的能源成本来推动先进的复合材料朝着循环经济发展。该项目的具体目标包括开发飞行员规模的过程，基于声学的表征工具的开发以及处理条件的优化，以确保电容器中使用的冷烧结复合材料的均匀性。将通过原位技术，特定的阻抗光谱，通过声学方法和机器学习支持的集成数据分析技术来获得有关过程优化的基础知识。优化的过程将使在降低温度下烧结的各种应用有价值，包括储能，结构材料，热管理和电子设备。研究，教育和劳动力发展的整合将是推进从实验室到商业制造业的冷界研究的关键。该项目由工程局CBET部门共同资助，以及数学和物理科学局的CHE部门，该奖项颁发了NSF的法定任务，并通过评估范围来反映了CRITIA的支持者，并反映了CRIT的支持。
