Question

Name the method of refining to obtain silicon of high purity

Answer 1

Hello,

Zone Refining is a process which is used to refine hard metals like silicon in the purest form. this process using metals in the rod shape and heats them on high temperature in a circular heater fitted around the rod which leads to melting the impurities in the rod.

I hope the answer helps you. thanks for asking.

Answer 2

Answer:

Explanation:

Zone refining to obtain silicon of high purity. Zone melting is a group of similar methods of purifying crystals. In which a narrow region of crystals is molten, and this molten zone is moved along the crystal and it is based on the principle that the impurities are more soluble in molten state than in solid state of metal.
