    摘要: The invention relates to a method for producing granular silicon by thermal decomposition of a gas containing silicon in a fluidized bed, said decomposition occurring in the presence of free-flowing mobile elements. Preferably, said free-flowing mobile elements become devoid of silicon in a separate procedural step, said silicon being deposited during decomposition of gas containing silicon, by reacting with hydrogen halides, halogens, alkyl halogenides, aryl halogenides or combinations of halogen and/or hydrogen halide and/or oxidized mineral acids and/or by thermal treatment of said elements.
