impurity zone
1Zone melting — is a method of separation by melting in which a molten zone traverses a long ingot of impure metal or chemical. In its common use for purification, the molten region melts impure solid at its forward edge and leaves a wake of purer material… …
2zone melting — a process of purifying any of various metals and other materials, as germanium or silicon, by passing it in bar form through an induction coil. Also called zone refining. Cf. cage zone melting. [1955 60] * * * Any of a group of techniques used to …
