Crystallization is a natural process which happens when the materials solidify from a liquid, or as they precipitate out of a liquid or gas. This process can be carried out by causing a physical change, like a change in temperature, or a chemical change like acidity. The crystallization process is carried out on the basis of the size and shapes ...
