Hightly pure metal can be obtained by zone refining

Highly pure metal can be obtained by zone refining

Semiconductor of very high purity can be obtained by zone refining. Explain the principle behind zone refining.

(A): High purity gallium for semiconducting purpose can be obtained by zone refining (R): Zone refining works on the principle of fractional crystallisation, leading to high purity

A: Ultrapure metals are obtained by zone refining. R: Van arkel method is used for purification of titanium

Assertion : Zone refining is based on the solubilities of impurities in the molten state than in the solid state of a metal. Statement : Pure metal oxide is obtained in zone refining.

Metals of high purity are obtained by zone refining. Impurities are more soluble in melt in pure metal.
