Question
Chapter 7, Problem 7.61E
Interpretation Introduction
Interpretation:
The reason as to why zone refining, used to make ultra-pure silicon, would not be a practical method of making ultra-pure carbon is to be stated.
Concept introduction:
Zone refining is a method that is used to form pure solid crystals of different substances. Zone-refining is based on the principle that impurities are more soluble in the molten state than in the solid state. The impure substance is placed on a heating belt which is moving continuously, a temperature gradient is maintained on the belt. The substance is melted on one side of the belt and gets cooled to solidify on the other side of the belt. The impurities remain in the molten state and a pure solid substance is obtained.
