Abstract

The kinetic processes relevant to up-gradient crystallization are analyzed in detail. Crystallization occurs upon moving an amorphous sample up through a temperature gradient which is the reverse of traditional crystallization from the melt. Both nucleation and growth processes are important to the present technique. To obtain a highly oriented microstructure, bulk nucleation must be prevented. Generally, a liquid with small nucleation rate and large crystal growth rate is favorable for the present route. The model was tested for the lithium diborate glass system, which yielded a highly oriented microstructure with only isolated additional nucleation events.
