Zone Refining Unit

Zone Refining Unit

Zone refining is a technique used to purify material with sharp melting points from 99.95% to 99.9999+% and above. 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%) also for organic compounds having sharp melting points. An automatic zone melting unit has been indigenously designed and developed with indigenous available components.
