A method is described for enhancing the formation of alkylhalosilane during the direct method reaction between powdered silicon and a catalyst comprising copper, zinc, tin, and phosphorus. An increase in the value of the Cu/Zn weight ratio has been found to promote the performance of the phosphorus-containing catalyst as shown by in an increase in the weight percent dimethyldichlorosilane in methylchlorosilane crude.
