Witryna1 sty 2024 · Recrystallization is of heterogeneous nature and thus exhibits something called “nucleation,” but which in fact implies growth of an existing subgrain of relatively low stored strain energy into surrounding material of relatively high stored strain energy. Various possible mechanisms of recovery and recrystallization are discussed. WitrynaIn chemistry, recrystallization is a technique used to purify chemicals. By dissolving a mixture of a compound and impurities in an appropriate solvent, either the desired compound or impurities can be removed from the solution, leaving the other behind. It is named for the crystals often formed when the compound precipitates out.
