. Describe the principle process involved in the purification of the metal by thisC) exteZóne Refining method

Answer» <p>Zone-refiningThis method is based upon the principle of fractional crystallisation, i.e., difference in solubilities of impurities in molten and solid state of metal. Semiconductors like silicon, germanium, gallium arsenideand indium antimonide are purified by this method. Elements of very high purity are obtained by this method..</p>
