Abstract
Disclosed is an apparatus for producing reduced silicon nanopowder, comprising: a housing having an inlet port on its top and an outlet port on its bottom; a motor installed in the housing; an annular raw material container installed inside the housing with raw material powder including silica and carbon being loaded and provided with an outer surface spaced apart from an inner surface of the housing, the raw material container rotating by receiving rotational force from the motor; and a laser beam generator for generating laser beams irradiated to the raw material powder of the raw material container through the inlet port. It is possible to load a large amount of raw material powder and thus produce more silicon nanopowder in a continuous process.
