Question

silicon tetrachloride is used:

• A. as an intermediate in the manufacture of high purity silicon
• B. in the semiconductor industry
• C. in the production of photovoltaic cell
• D. all of the above

Answer 1

The correct option is D all of the above

Silicon tetrachloride is used as an intermediate in the manufacture of high purity silicon, since it has a boiling point convenient for purification by repeated fractional distillation. Very pure silicon derived from silicon tetrachloride is used in large amounts in the semiconductor industry, and also in the production of photovoltaic cell.
