摘要： A process for preparing granular polysilicon using a fluidized bed reactor is disclosed. The upper and lower spaces of the bed are defined as a reaction zone and a heating zone, respectively, with the height of the reaction gas outlet being selected as the reference height. The invention maximizes the reactor productivity by sufficiently providing the heat required and stably maintaining the reaction temperature in the reaction zone, without impairing the mechanical stability of the fluidized bed reactor. This is achieved through electrical resistance heating in the heating zone where an internal heater is installed in a space in between the reaction gas supplying means and the inner wall of the reactor tube, thereby heating the fluidizing gas and the silicon particles in the heating zone. The heat generated in the heating zone is transferred to the reaction zone by supplying the fluidizing gas at such a rate that the silicon particles can be intermixed between the reaction zone and the heating zone in a continuous, fluidized state.

摘要： The present invention relates to a method a method for continuous preparation of a well dispersed spherical hydrous zirconia particles with an average diameter(dp) of 1˜1,000 nm in the form of sol solution, which method comprises continuously supplying the aqueous solution of a zirconium salt at a concentration of 0.001˜0.5 mole/l to a reactor consisting of one or more than two reaction tubes at a temperature of less than 25° C., heating the said aqueous solution in the reactor(s) in a continuous flow state up to the boiling point, and then discharging the said solution through the outlet of the said reactor(s). Contrary to the method employing a conventional batch-type reactor or semi-continuous stirred-type reactor, the method for continuous preparation of a hydrous zirconia sol according to the present invention can allow various operational parameters to be controlled in a certain range and thus contributes to remarkably improve the quality of a hydrous zirconia sol to be prepared or of the zirconia powder obtainable as a final product.
