Zone Refining - VEL INNOVATIVE TECHNOLOGIES PVT LTD

Zone refining is the most important of the zone-melting techniques. It is being widely used in the semiconductor industry for refining of germanium and silicon to purity levels of 9N and above (i.e. >=99.9999999%). The Induction Zone Refining technique involves melting a narrow zone of a long ingot of the material to be processed.

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

What Is Zone Refining?

Zone refining is a technique companies can use in the production of highly pure crystals for components like transistors. In this method, impurities in an ingot, or mass of metal, are forced to one end or another through a series of melting and cooling phases.

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.
