‘Blue Skies, Green Future’ Webinar: Cold Sintering of Functional Materials
Wednesday 12 May 2021
Professor Clive Randall discuss the fundamentals of cold sintering as well as some new examples of this technology across different material
The ‘Blue skies, green future’ webinar series presents ideas to spark discussion on the topic of transformation and innovation within the foundation industries.
Webinars will take place each month and with novel ideas and concepts presented by a world-leading researcher in the field. During the session, speakers will discuss a technology which if implemented could transform the foundation industries. The goal is to encourage the audience to consider ways in which their own industry can utilise and embed innovation.
This session will be a presentation from Professor Clive Randall on the cold sintering of functional materials.
Cold Sintering involves a transient phase that permits the densification of particulate materials at low temperatures 300 o C and below. Sintering at such low temperature offers so many new opportunities. It permits the integration of metastable materials that would typically decompose at high temperatures. So cold sinter enables a platform for better unification of material science. Now ceramics, metal and polymers can be processed under a common platform in one step processes. With controlling the forming process new nanocomposites can be fabricated. Polymers, gels and nanoparticulates can be dispersed, interconnected and sintered in the grain boundaries of a ceramic matrix phase. With the ability to sinter metal phases, multilayer devices can be co-sintered with electrodes made from metals such as Al, Ag, Fe and Cu. With appropriate binder selection, polypropylene carbonate and its de-binding at 130 o C we can remove organic binders and leave metals and other more stable polymers within the layers that then can be co-sintered under the cold sintering process and form unique combinations of materials in multilayers. This talk will cover some of the fundamentals of cold sintering, as well as some new examples of this technology across different material systems, ranging from ferroelectrics, semiconductors, and battery materials.
Professor Clive A. Randall is a Distinguished Professor of Materials Science and Engineering and Director of Materials Research Institute at The Pennsylvania State University. He has a B.Sc. (Honors) in Physics from University of East Anglia, UK (1983), and a Ph.D. in Experimental Physics from University of Essex, UK (1987). He was Director for the Center for Dielectric Studies 1997-2013, and Co-Director of the Center for Dielectrics and Piezoelectrics 2013-2015 (now Technical Advisor). Interests include discovery, processing, material physics, and compositional design of functional materials. Among his awards are Fellow of the American Ceramic Society, Academician of World Academy of Ceramics, IEEE Distinguished Lecturer, and honorary Fellow of the European Ceramic Society. Prof. Randall has a Google h-factor of 85 and over 25,000 citations.
About the Network
The TFI Network aims to assist the foundation industries to remain competitive whilst simultaneously facing challenges from environmental legislation and the drive towards net-zero carbon 2050. Launched in February 2021, the core aim of TFI Network+ is to co-create with the Foundation Industries new science and technology that can transform their sustainability and performance by coordinating and channelling a wide range of expertise throughout UK academia in themes such as energy efficiency, circular economy, new generation processes and manufacturing informatics.
TFI Network is funded by Engineering and Physical Science Research Council. The Network offers small project grants to support research, transformation and collaboration across the six sectors of the foundation industries. Becoming a member of the Network allows you to advertise your expertise or business requirements to other members, identify other members who may have similar research areas for collaboration and submit applications for small project grants.
