WebCrystal studies are important in physics, biology, particularly in virology. Improvements in contemporary metallurgy and the chemical, ceramic, and other industries depend to a large extent on a thorough knowledge of crystallization processes. A crystal growing from an impure solution is itself much purer than the solution. WebSep 30, 2024 · What Does Recrystallization Mean? Recrystallization is the process in which deformed grains of the crystal structure are replaced by a new set of stress-free grains that nucleate and grow until all the original grains have been consumed. The process is accomplished by heating the material to temperatures above that of crystallization. great nurse practitioner
