Early Stage Crystallization Kinetics of Lithium Disilicate and Sodium Silicate Glasses

摘要

Crystallization kinetics of glasses remains an active area of inquiry due to its technological and scientific importance. In the realm of technology, knowledge of crystal nucleation and growth rates in glasses at different temperatures is essential for preparing glass-ceramics, where promoting and controlling nucleation and growth of the desired crystal phases in the desired proportions offers a means of tailoring the properties of the final material. Knowledge of crystallization kinetics is also vital for predicting glass stability in applications where crystallization must be avoided, such as optical fibers, where crystal nucleation and growth would degrade the performance of the material. Understanding transformation kinetics is also important for preparing novel glasses with unique properties, for instance, to aid in determining the quench rate necessary to obtain an amorphous form of a given substance, e.g. metallic glasses.
