摘要： Silicon-containing materials along with process for producing and uses for the same. The process includes reacting the silicon-containing materials in a fluidized bed reactor by deposition of silicon from at least one silicon precursor in pores and on the surface of porous particles. A fluidizing gas stream is provided within the fluidized bed reactor that is fully or partly induced to oscillate in a pulsed manner and propagates in the form of a wave and acts on the fluidized bed so as to form a homogeneously fluidized bed as a pulsed gas stream so as to form a homogeneously fluidized bed having a fluidization index FI of at least 0.95. Where the fluidizing gas stream has a superficial velocity which is above a measured minimum fluidization velocity of the pulsed gas stream and where the pulsation is combined with mechanical stirring as a further fluidizing aid.
