Abstract

This invention provides a reactor for producing a silicon material for a solar cell, which can produce a silicon material for a solar cell at low cost in a continuous manner. Silicon having a diameter of several tens of micrometers to several hundreds of micrometers is continuously produced by a zinc reduction reaction of silicon tetrachloride with gasified silicon tetrachloride and gasified zinc. A reacting furnace (1) comprises a reaction chamber (2) and an output chamber (3) for withdrawing the produced silicon. A number of holes for supplying zinc is provided on a bottom plate (6) in a reaction chamber (2). Silicon tetrachloride is supplied into the reaction chamber (2) through an introduction pipe (21a) which stands up from the bottom plate (6). Further, a silicon seed, together with a carrier gas, is supplied into the reaction chamber (2) to promote the precipitation of granular silicon.
