Title:
METHOD FOR PRODUCING SILICON MICROPARTICLES
Document Type and Number:
Japanese Patent JP2012041230
Kind Code:
A
Abstract:
To provide a method for efficiently producing silicon microparticles having a uniform particle size.
The method includes: 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 the 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.
