Beskrivelse

Edgar D. Zanotto, Federal University of São Carlos, Brazil

All inorganic, metallic, and organic supercooled liquids (SCL) tend to crystallize. Whether or not they crystallize on the cooling path from the liquid state (temperatures above the liquidus) is the key issue for successful vitrification. On the other hand, several glasses can be made by fast cooling, shaped into different forms, and then crystallized via controlled thermal treatments. This is the most common way to produce glass-ceramics (GCs), which have been increasingly used in a plethora of domestic and high applications, such as in chemical, electronic, optical, dental and medical materials and devices. Due to this vast scientific and technological importance, “crystallization” has been the most frequently used keyword in the past 200 years of reported glass research.

In this seminar, we dwell on experimental, theoretical and computer simulation efforts that have been made in the past 70 years to unveil the intricate details of crystal nucleation in glass-forming liquids. I will keep the results as a surprise to the interested attendees who are bold enough to attend and stay put in my lecture until the end...
