Abstract
A contact mass for use in the synthesis of organohalosilanes is prepared by adding metallic copper particles to metallic silicon particles, and rubbing the particles against each other under high shear forces in a non-oxidizing atmosphere, thereby forming a metallic copper thin film on the surface of the metallic silicon particles in a spot pattern or entirely. The contact mass is capable of reducing the time required for activation and has an extended lifetime.
