METHOD FOR PRODUCING SILICON FINE PARTICLES |
摘要 |
A method for producing silicon microparticles comprises: a burning step for burning a mixture including a silicon source and a carbon source in an inert atmosphere; a rapid cooling step for rapidly cooling gas generated by burning the mixture, and for obtaining a composite powder including silicon microparticles and silicon oxide; a heating step for heating the composite powder in an oxidative atmosphere; and a removal step for removing silicon monoxide and silicon dioxide from the heated composite powder.
