recrystallizing
Purifying by dissolution
Recrystallizing is the process of forming crystals again, typically to purify a substance.
In chemistry, a compound is dissolved in hot solvent and allowed to cool slowly, so impurities stay in solution while purer crystals form: After recrystallizing the compound twice, we achieved 99% purity.
Metals recrystallize when heated, forming new grain structures that relieve internal stress.
