Abstract
Chlorosilanes of the general formula HSiCland/or HClSi, where n=1-4 and m=0-4, are produced in a fluidized bed reactor by reaction of a hydrogen chloride-containing reaction gas with a silicon contact mass granulation mixture composed of a coarse grain fraction and a fine grain fraction, wherein the average particle size of the fine grain fraction dis smaller than the average particle size of the coarse grain fraction d.
