A process for preparing halogen-containing silanes from the direct reaction of silicon and a hydrogen halide or an organic halide in which the performance of a fluid bed reactor system is improved by the addition of an inert solid. The addition of an inert solid, such as sand, facilitates improved control of reaction temperature, and as a result improves silicon raw material efficiency while maintaining the desired produt distribution in the crude halosilanes or organohalsilanes. |
