Abstract
A production method, comprising a step of synthesizing silicon particle-containing silicon oxide particles by performing a gas phase reaction of monosilane gas and oxidizing gas for oxidizing the monosilane gas and a step of removing the silicon oxide with hydrofluoric acid after holding the silicon oxide particle powder in an inert atmosphere at 800-1400° C., provides high-purity silicon nanoparticles which are highly practical as material powder for high-performance light-emitting elements and electronic parts in an industrial scale.
