Refining Of Metals Distillation Zone Refining
Zone refining is a special method we use to purify metals. It was the invention of William Pfann. It purifies metals to a very high degree. A rod of impure metal is placed in a container which we fill with inert gas. Then we place a circular heater around the rod at the top. The impure metal heats up due to the circular heater.
Zone Refining Principle And Process Of Purifying Metals
Zone refining is a very useful method to get metals with very high purity such as silicon and germanium. It is also referred to as zone melting, floating zone process, and travelling melting zone. What is Zone Refining Zone refining refers to the method of purifying a crystal wherein a thin region of the crystal undergoes melting.
