Abstract:
    What is disclosed is a method of improving the performance of the direct process for preparing alkylhalosilanes using an alkylhalide and silicon. The method is based on the control of the phosphorus that enters the silicon used in the direct process, by controlling the amount of phosphorus that enters the silicon during the manufacture of the silicon itself.
