Zone melting - Wikipedia

Zone melting (or zone refining or floating-zone process or travelling melting zone) is a group of similar methods of purifying crystals, in which a narrow region of a crystal is melted, and this molten zone is moved along the crystal. The molten region melts impure solid at its forward edge and leaves a wake of purer material solidified behind it as it moves through the ingot. The impurities concentrate in the melt, and are moved to one end of the ingot. Zone refining was invented by John Desmond Bernaland furthe…

Zone Refining - Principle and Process of Purifying Metals ...

18-02-2019· Zone refining refers to the method of purifying a crystal wherein a thin region of the crystal undergoes melting. This ‘molten zone’ is now moved across the crystal. The impurities in the metal are melted at the forward edge by the molten zone and move through the block of metal, leaving the solidified pure element behind.

Zone melting | industry | Britannica

17-08-2020· Zone refining achieves the same result very simply. A series of molten zones traverse the ingot in the same direction, usually through a series of heaters, as suggested in Figure 1B. Each zone takes in impurity at its melting interface and freezes out solid purer than the liquid at its freezing interface.

High-Speed Zone Refining | American Laboratory

Zone refining is a process in which organic and inorganic compounds are purified. 1 Like distillation and gas and liquid chromatography, zone refining is dependent on the distribution of material between two phases. However, the distribution in zone refining is between the solid and liquid phases, while the distribution in distillation and gas chromatography is between the liquid and vapor phases.
