Melt crystallization is a thermal separation and purification technique in chemistry in which a substance is selectively solidified from its own melt (i.e., without a solvent) by exploiting differences in the solid–liquid phase equilibria of the components in a mixture. By controlling temperature so that only the target compound crystallizes while impurities or co-existing components remain in the liquid phase, a high-purity solid product can be obtained.
