  • zone refining wilcox major reference works wiley

    Zone refining is one of a class of techniques known as fractional solidification in which separation is brought about by crystallization of a melt without solvent being added. Zone refining was developed in response to the need for extremely pure germanium. It can be applied to almost every type of substance that can be melted and solidified
