Preparation of silicon from silica sand and how silicon is purified for use in semiconductor devices needed to be described and chemical reactions involved. Concept introduction: Silicon is generally obtained from silica sand. Silica sand it is naturally abundant material it is found in the form of rock clay and sand and more than half the earth’s crust are made of silica is very useful semiconductor and is the key ingredient in every computer processor. Its oxides form knows as silica or quartz. Silica sand is silica oxides so pure silica can be obtained by reduction process. Either by C or Mg . Convert silica into volatile substance which is fractional distillate and then it is converted back to elemental silicon by reduction.
