Instructor: Edgar Zanotto, Center for Research, Technology and Education in Vitreous Materials, Federal University of São Carlos, Brazil
Learn the popular predictive theories of nucleation, growth, and overall crystallization
After completing the course and homework, participants will learn how to apply these theories to avoid spontaneous devitrification to produce new glasses, as well as start designing some glass-ceramics having simple nano or microstructures.

This course is aimed at those interested in an updated, high level, introduction to the intricate (dynamic and thermodynamic) processes that control crystal nucleation, growth and overall crystallization of glasses, including industry professionals, post-graduates, and undergraduate students. This knowledge is key to the production of novel glasses and for the development of new or improved glass-ceramics. It is recommended that the participants have a significant background in materials science or engineering, chemistry or physics. Previous knowledge and experience in glass science would be beneficial.
- Relevance of crystal nucleation, crystal growth and overall crystallization for the understanding of the vitreous state, as well as for glass and glass-ceramic technology.
- Crystal nucleation in glass-forming liquids: phenomenology, experimental methods, homogeneous and heterogeneous nucleation, surface crystallization, non-steady state effects, classical nucleation theory (CNT), experimental tests of CNT, metastable phase formation, temperature and size dependent surface energy, the courtyard effect, the effect of elastic stresses, maximum nucleation rates (Imax) versus glass transition temperature (Tg).
- Crystal growth in glass-forming liquids: growth models, experimental methods (OM, DSC, etc.), tests with several glasses, growth rate maxima, Umax vs. Tgr, the breakdown of the Stokes-Einstein-Eyring equation.
- Overall Crystallization: JMAK (Johnson-Mehl-Avrami-Kolmogorov) – model, experimental methods, tests with some glasses.
- Glass-ceramics (GC): Historical development, existing glass-ceramics, new GC that are yet in the development stage, such as: large grain transparent GC, bioactive GC, sintered GC, PTRG and Laser crystallized GC
- Micrograph gallery: Chemical and physical phenomena revealed by beautiful micrographs of crystals in glass.
