Zone refining

Vedclass · Answer

(B) The principle of $Zone \ refining$ is that the impurities are more soluble in the melt state than in the solid state of the metal. As the heater moves,the pure metal crystallizes out of the melt,while the impurities pass into the adjacent molten zone. This method is particularly useful for producing semiconductors like $Ge$,$Si$,$Ga$,and for the purification of elements like $Boron$ $(B)$. Therefore,the correct option is $B$.

The solubilities of the impurities in the melt and solid states are not the same. This principle is applied during the extraction of boron. This method is known as:
