Fluidized bed reactor systems and distributors are disclosed as well as processes for producing polycrystalline silicon from a thermally decomposable silicon compound such as trichlorosilane. The processes generally involve reduction of silicon deposits on reactor walls during polycrystalline silicon production by use of a silicon tetrahalide.
