Question

What is recrystallization?

Answer 1

Recrystallization is a physical method which is used to purify chemicals based on their different solubility’s. The process is completed with heating the material to dissolve the compound with impurities with the a mixture of a suitable solvent. With this process we can extract the desired compound or impurities from the mixture.
This process is applied in the hardening of steel, to remove all the effects of strain hardening such as substantial plastic deformation produced during cold working.
