Abstract

A process for preparing trichloromonosilane, in which silicon particles are reacted with hydrogen chloride in a fluidized bed reactor, wherein the silicon particles used are a silicon dust which is obtained as a waste product in the preparation of defined silicon particle size fractions from lump-form silicon and the silicon dust is introduced directly into the reactor.
