<P> In chemistry , recrystallization is a technique used to purify chemicals . By dissolving both impurities and a compound 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 . Alternatively , recrystallization can refer to the natural growth of larger ice crystals at the expense of smaller ones . </P>
