The Amazing Properties of Glass-Ceramics (GC Part 1)

The video discusses how the property of "zero-expansion" is achieved in glass-ceramics. 00:00 Intro 01:10 The discovery of glass-ceramics at Coning 02:12 Thermal shock exeriments 06:46 Coefficient of thermal expansion explained 10:12 Measuring CTE if glasses and glass-ceramics (experiment) 14:05 CTE measurement results 17:11 creating negative and zero CTE 20:17 Crystallization and nucleation 22:25 How glass-ceramics are made in practice 25:14 How to make crystallites visible (experiment) 26:15 light scattering in glass ceramics (+ simulation) If you want to know more about this subject, I would suggest a book by Bach (editor) et Al. named "Low Thermal Expansion Glass Ceramics" Publised by Springer. ISBN 3-540-58598-2. It's quite expensive and rare but occasionally it is offered second hand at reasonable prices. The wave simulations at the end of the video were made using the script published by @DiffractionLimited. To try this yourself download the script from: https://github.com/0x23/WaveSimulator2D I displayed several 3rd party images under fair use policy.
