Abstract
In a process for preparing oganohalosilanes by reacting metallic silicon particles with an organohalide in the presence of a copper catalyst, a contact mass composed of the metallic silicon and the catalyst further contains a minute, but effective amount of a catalytic metal powder which has been produced by an atomizing technique. The process is successful in drastically increasing a formation rate without lowering the selectivity of useful silane.
