The 12th "International Symposium on Crystallisation in Glass and Liquids" of the International Commission on Glass (ICG) took place from 10th to 13th September 2017. This year the triennial symposium met in the historical metropolis of Segovia near the Spanish capital. The conference programme included numerous presentations, some of them by renowned personalities, and a poster session with 76 posters.
Tina Waurischk and Carsten Blaeß from the Glass Division represented BAM in the poster competition. They recounted aspects of their Ph.D. theses prepared at BAM to the international audience, and both of them were recognised for their scientific posters.
Tina Waurischk presented an impressive poster entitled "A new device for inert subcritical crack growth measurements in crystallised glasses" which dealt with crack growth in glass and the influence of glass individual components. She presented a newly developed chamber to investigate slow-growing cracks in different environments and under vacuum. Her work is part of a research project within the German Research Foundation’s (DFG) "Topological engineering of ultrastrong glasses" Priority Programme (SPP 1594) in collaboration with the Clausthal University of Technology and the Leibniz University of Hannover.
Carsten Blaeß’s poster "Crack healing in glass matrix composites" described his research into crack healing in glass and glassy-crystalline microstructures. He investigated the influence of the microstructure on the duration and progress of crack healing. This work was triggered by cracks in solder glass following thermal or mechanical stress, for example, in high-temperature fuel cells during heating and cooling processes.
Dr. Ralf Müller, Head of BAM’s Glass Division, was elected Deputy Head of the ICG Technical Committee 07 (TC07) "Crystallisation and glass ceramics" at the symposium.
